10 Mistakes Of Science We Get From School

10 Mistakes Of Science We Get From School

There are some misunderstandings in the implementation of science in public that need to be corrected truth.
Here there are approximately 10 misconceptions about science that circulate in the community.

1. Water IS blue, not Just Because of the Sky
(Blue colored water caused not only a reflection of the sky)

 

Many believe that the lake and the blue sea "Only" because they reflect the blue sky. Actually, the water looks blue because they are really blue. Water molecules absorb light, and they absorb red frequencies more than the frequency of blue, so the frequency of blue appeared on the surface. Effect was small, so the color blue to be seen more clearly when observing layers of water or in dense enough. In salt water or mineral springs, mineral colors of decay can be seen.

Perefleksian color of the sky also provides a role for the blue ocean, but only when surface water is very calm and only when water was observed with a small kesudutan around 10 degrees.

  2. Electricity does NOT travel at the speed of light

(Electrik / electricity does not travel at the speed of light)

 

Many textbooks claim that the electricity (electrons) flow through the cable runs at the speed of light. The fact is, the energy of fast flowing elektriklah (which is still slower than the speed of light). Electrons, which has mass, can move at the speed of Beautiful light by using the theory of relativity. The speed of the electric charge in electric current is very slow, around several centimeters per hour. In places where electric currents can be seen, as in electrophoresis, slow movement of the carrier can be seen directly.

3. Seasons are NOT the Same length
(Season deemed to have the same time period)

 

Because the earth moves faster in its orbit as it approached the sun, summer in the southern part of the earth / winter in the northern part of the earth is the shortest time for the season, with summer in the north or south of the longest winter. However, the difference is only felt a few days, while on Mars with an eccentric orbit, the difference was huge.

4. You will not get a cold a just from low temperature
(You will not get the flu from the cold only)

 

Has become a widespread misconception in the public that the common cold can be caused by cold weather. Reality, the common cold is caused by a virus and has nothing to do with low temperature or cold.

5. Saturn is NOT the only planet with rings
(Saturn is not the only planet that has rings)

 

 

Jupiter, Uranus, and Neptune also have rings around them, although that was in Saturn's rings are the most obvious and easily seen.

6. Pls are NOT hot meteors land on Earth they want
(Meteors are not hot when it landed on earth)

 

 When a meteor landed on earth, meteors are usually not hot like most of the meteor in Hollywood movies. Usually, only warm. Meteor velocity sufficient to melt the outer surface, but the material that melts quickly separated, and the interior of the meteor did not have time to heat up because rocks are poor heat conductors.

7. Clouds do NOT form Because of the water's temperature
(The cloud is not formed due to the influence of air temperature)

 

Is the wrong knowledge that the clouds are formed from the cold "hold" less water vapor than warm air. Air does not have the capacity to contain water vapor. Only the temperature of the water itself (and vicinity) which causes the humidity, condensation process, and then the formation of clouds.

8. People DID know Earth was not flat before Columbus
(People already knew the earth was not flat before Columbus)

  

Some believe that Christopher Columbus had difficulty in receiving support because the people of Europe believe that the earth was flat. In fact, sailors and navigators at that time knew that the earth is round, but (correct knowledge) do not agree with estimates from Columbus of the distance to India. If America does not exist, and Columbus went on his journey to India that actually, he will not be able to survive longer to achieve.

 

9. The Great Wall of China is NOT particularly visible from space
(China Great Wall not visible from space)

  At the time in low orbit, the Great Wall of China can be seen from outer space but not as unique from the digembor rant. From the low earth orbit, many artificial objects can be seen on earth, not just the Great Wall of China. Highways, ships at sea, dams, railways, cities, rice fields, and several buildings.

As has been claimed that the Great Wall of China is a man-made objects are visible on the Moon, Apollo astronauts have reported that they did not see any human-made object from the moon.

10. There is NO "dark side" of the Moon
(There is no dark side (which is always dark) of the month)

 
Months in orbit synchronous (synchronous orbit), this means, the moon menmbutuhkan exactly the same time to rotate once on its axis with the rotation of the earth. So the moon has the far side / rear / dark / outside, because it always gives the same to the earth's surface when it rotates. When the moon is estimated to be between the Sun and Earth, it dalah time "lunch" at the far side / outside / back of the moon and the night for the side facing the earth. When the Earth between the sun and moon, the part that much experience when "night" and "lunch time" for the part which faces the earth.

Seven Technologies That Will Rock 2011

Seven Technologies That Will Rock 2011

So here we are in a new decade, and the technologies that are now available to us continue to engage (and enthrall) in fascinating ways. The rise and collision of several trends—social, mobile, touch computing, geo, cloud—keep spitting out new products and technologies which keep propelling us forward. Below I highlight seven technologies that are ready to tip into the mainstream 2011.

Before I get into my predictions, let’s see how I did last year, when I wrote “Ten Technologies That Will Rock 2010.” Some of my picks were spot on: the Tablet (hello, iPad), Geo (Foursquare, Gowalla, Facebook Places, mobile location-aware search, etc.), Realtime Search (it became an option on Google) and Android (now even bigger than the iPhone). Some are still playing out: HTML5 (it’s made great strides, but isn’t quite here yet), Augmented Reality (lots of cool apps have AR functionality, but for the most part it is still a parlor trick), Mobile Video (FaceTime and streaming video apps pushed it forward), Mobile Transactions (Square and other transaction processing options came onto the scene), and Social CRM (Salesforce pushed Chatter, and tons of social CRM startups pushed their wares, but enterprises are always slow to adopt). And one got pushed to 2011: Chrome OS (we are still waiting).

What’s in store for 2011? Some of these themes will continue to evolve, and some new ones will gain currency. Here are seven technologies poised to rock the new year:

1. Web Video On Your TV: We’ve already seen many attempts to turn the Internet into a video-delivery pipe to rival cable TV: Google TV, Apple TV, the Boxee Box, Roku, and a slew of “Internet-enabled” TVs.  None of them are quite yet cable killers, but they are seeding the market with simple ways to bring Internet video to your large-screen TV in the living room. The more cable-quality video that becomes available over the Web via streaming services such as Netflix, Vudu, or iTunes, the more that people will turn to Web when they are looking for something to watch. This trend is not about surfing the Web on your TV. Nobody wants to do that. It is about using the Internet as an alternative way to deliver movies and TV shows to your flat-screen TV. Even the cable companies will dip their toes into the Internet delivery waters (or plunge deeper if they already have their toes wet). What looks like a pale competitor to cable today will be a lot more viable in a short, twelve months.
2. Quora Will Have Its Twitter Moment: Social Q&A site Quora may be the current darling of Silicon Valley, but not a lot of people beyond the insular tech startup world actually use it yet. That will start to change in 2011, which I believe will be the year Quora has its Twitter moment and start to really take off. Quora represents a bigger technology trend, which is the layering of an interest graph on top of people’s social graph. On Quora, you can follow not only people, but topics and questions. It defines the world by your interests, not just the people you may know or admire. This is a powerful concept and is not limited to Quora (both Twitter and Facebook also want to own the interest graph), but Quora is designed from the ground up to expose and help you explore your interests. It is addictive, and as it reaches a critical mass of early users, this will be the year it emerges from its shell much like Twitter did in 2007.
3. Mobile Social Photo Apps:The end of 2010 witnessed a spate of mobile photo apps including Instagram, PicPlz and Path. They all take advantage of several massive key trends: the growth of iPhone and Android, the ubiquity of decent cell phone cameras, GPS, and existing social networks like Facebook, Twitter, and Foursquare. Each of these apps is built for mobile first. They let you take a picture, mark your location, and share it with your social network (sometimes public, sometimes private). With Instagram and PicPLz, you can choose a filter to make humdrum pics look more exciting or capture a mood. By building on top of existing social networks like Twitter and Foursquare, they are making popular new ways to use those services. Instead of simply checking in, now you can do a photo checkin (even Foursquare lets you do that now). Already Instagram is one of the most popular photo apps in iTunes. Sharing photos is pretty much a universal impulse, and these apps make it easier and more fun.
4. Mobile Wallets: If you could use your cell phone as a credit card, would you? Everyone from Apple and Google to Nokia want to make that a reality and tap into the mobile payments market. Both Apple and Google are exploring this opportunity. Google bought mobile payments startup Zetawire to gain experience and the latest Android phone, the Nexus S, comes with an NFC chip—the same kind that is embedded into credit cards and lets you pay by waving it over a wireless reader. The iPhone 5 also may come equipped with an NFC chip, and Apple was sniffing around mobile payments startup BOKU last year for a possible acquisition. It is going to take more than just NFC chips in every phone to make mobile payments a reality, but efforts by the major players this year should begin to move the needle.
5. Context-Aware Apps: Whether it’s search, mobile, or social apps and services, the most useful apps people will keep coming back to are the ones which help people cut through the increasing clutter of the Internet. Apps that are aware of the context in which they are being used will serve up better filtered information. When you search on your mobile phone, that means you get local results and local offers served up first. If you are on a service like Quora that understands your interest graph, it means that you are only shown topics that you care about, sorted in realtime. If you are on a news site, you will see the most shared links from people in you follow on Twitter or are connected to on Facebook. Music and movie services will similarly surface social recommendations. In a world of information overload, context is king.
6. Open Places Database: Every mobile app, it seems, taps into the geo capabilities of phones to pinpoint your exact location and show you what is around you. (Incidentally, that is another example of a context-aware app). But there is a lot of duplication going on, with everyone from Google to Facebook to Foursquare creating their own database of places. It would make much more sense if there was an open places database that any company could both pull from and contribute to. While we are not there yet, we are making progress towards a more open places database, or at least a federated one. Factual is providing some of the data for Facebook Places and creating a places database is a major focus for the company; MapQuest (owned by AOL, as is TechCrunch) is adopting OpenStreetMaps (which could very well become the central places database with more resources and development); and Foursquare lets other apps pull from its places database through its API. There are economic reasons why some companies don’t want to participate (controlling the places database makes it easier to serve up local offers), but expect to see this movement pick up steam in 2011.
7. The Streaming Cloud: As all media moves to the cloud, more and more people will stream their movies and music whenever they want to any device. I’ve already mentioned the forces that will bring Web video streaming to your TV, but those movies and TV shows should also be available on your iPads, Android Tablets, or even mobile phones if you want. Expiring downloads will still make sense for plane trips and other places where the network is spotty, but you will manage your subscriptions and collections in the cloud. Think Netflix streaming applied to all media. If Google or Apple can convince the record companies to come along for the ride, the streaming revolution will hit music as well, with both working on jukebox-in-the-sky services. Why would you want to bother with managing all the download rights for the songs you buy from iTunes between your iPhone, iPad, laptop, and your wife’s computer, when you could just sign in form anywhere and start streaming? Plenty have tried with varying degrees of success and failure (Rhapsody, Rdio, Spotify), but it will take someone with the negotiating muscle of Apple or Google to finally bring streaming music to the masses.

What technologies do you think will make it big this year?

 Android Technology

 

        Android is a software stack for mobile devices that includes an operating system, middleware and key applications. The Android SDK provides the tools and APIs necessary to begin developing applications on the Android platform using the Java programming language.

Features

• Application framework enabling reuse and replacement of components
• Dalvik virtual machine optimized for mobile devices
• Integrated browser based on the open source WebKit engine
• Optimized graphics powered by a custom 2D graphics library; 3D graphics based on the OpenGL ES 1.0 specification (hardware acceleration optional)
• SQLite for structured data storage
• Media support for common audio, video, and still image formats (MPEG4, H.264, MP3, AAC, AMR, JPG, PNG, GIF)
• GSM Telephony (hardware dependent)
• Bluetooth, EDGE, 3G, and WiFi (hardware dependent)
• Camera, GPS, compass, and accelerometer (hardware dependent)
• Rich development environment including a device emulator, tools for debugging, memory and performance profiling, and a plugin for the Eclipse IDE

Android Architecture

The following diagram shows the major components of the Android operating system. Each section is described in more detail below.

Applications

Android will ship with a set of core applications including an email client, SMS program, calendar, maps, browser, contacts, and others. All applications are written using the Java programming language.

Application Framework

By providing an open development platform, Android offers developers the ability to build extremely rich and innovative applications. Developers are free to take advantage of the device hardware, access location information, run background services, set alarms, add notifications to the status bar, and much, much more.
Developers have full access to the same framework APIs used by the core applications. The application architecture is designed to simplify the reuse of components; any application can publish its capabilities and any other application may then make use of those capabilities (subject to security constraints enforced by the framework). This same mechanism allows components to be replaced by the user.
Underlying all applications is a set of services and systems, including:

• A rich and extensible set of Views that can be used to build an application, including lists, grids, text boxes, buttons, and even an embeddable web browser
• Content Providers that enable applications to access data from other applications (such as Contacts), or to share their own data
• A Resource Manager, providing access to non-code resources such as localized strings, graphics, and layout files
• A Notification Manager that enables all applications to display custom alerts in the status bar
• An Activity Manager that manages the lifecycle of applications and provides a common navigation backstack

For more details and a walkthrough of an application, see the Notepad Tutorial.

Libraries

Android includes a set of C/C++ libraries used by various components of the Android system. These capabilities are exposed to developers through the Android application framework. Some of the core libraries are listed below:

• System C library - a BSD-derived implementation of the standard C system library (libc), tuned for embedded Linux-based devices
• Media Libraries - based on PacketVideo's OpenCORE; the libraries support playback and recording of many popular audio and video formats, as well as static image files, including MPEG4, H.264, MP3, AAC, AMR, JPG, and PNG
• Surface Manager - manages access to the display subsystem and seamlessly composites 2D and 3D graphic layers from multiple applications
• LibWebCore - a modern web browser engine which powers both the Android browser and an embeddable web view
• SGL - the underlying 2D graphics engine
• 3D libraries - an implementation based on OpenGL ES 1.0 APIs; the libraries use either hardware 3D acceleration (where available) or the included, highly optimized 3D software rasterizer
• FreeType - bitmap and vector font rendering
• SQLite - a powerful and lightweight relational database engine available to all applications

Android Runtime

Android includes a set of core libraries that provides most of the functionality available in the core libraries of the Java programming language.
Every Android application runs in its own process, with its own instance of the Dalvik virtual machine. Dalvik has been written so that a device can run multiple VMs efficiently. The Dalvik VM executes files in the Dalvik Executable (.dex) format which is optimized for minimal memory footprint. The VM is register-based, and runs classes compiled by a Java language compiler that have been transformed into the .dex format by the included "dx" tool.
The Dalvik VM relies on the Linux kernel for underlying functionality such as threading and low-level memory management.

Linux Kernel

Android relies on Linux version 2.6 for core system services such as security, memory management, process management, network stack, and driver model. The kernel also acts as an abstraction layer between the hardware and the rest of the software stack.

 

Best/Beautiful Flash Websites

 Best/Beautiful Flash Websites

Flash, enabled web designers to deliver content in a very interactive and creative way. Many people dream about jazzy websites that convey their message by using dynamic animation. Getting inspiration for developing flash websites is not an easy job for web designers. Designers should have deep conceptual / functional knowledge of a company for which they are designing flash websites and that’s the main reason for expensiveness of these websites.

In the showcase below, I am going to list some flash websites that will definitely engage your interest and mesmerize you by their unbelievable creativity.

20 Great Ways to Find More Free Time

20 Great Ways to Find More Free Time

 

Are there a hundred different things you wish you could do with your life someday — anything from exercising to meditation or yoga to writing that novel you always wished you could write to reading more to relaxing and watching the sunrise? But perhaps you never have the time, like most people.
The truth is, we all have the same amount of time, and it’s finite and in great demand. But some of us have made the time for doing the things we love doing, and others have allowed the constant demands and pressures and responsibilities of life to dictate their days.
It’s time to move from the second group back into the first. Reclaim your time. Create the life you want and make the most of the free time you lay claim to. It’s not hard, though it does take a little bit of effort and diligence.

Not all of these will be applicable to your life — choose the ones you can apply and give them a try:

1. Take a time out. Freeing up your time starts with taking a step back to take a good look at your life. You need to block off at least an hour. Several hours or half a day is better. A whole day would be awesome. A weekend would be even more ideal, though not necessary practical for many folks. With this block of time, take a look at your life with some perspective. Is it what you’ve always wanted? How would you get to where you’ve always wanted to be? What do you enjoy doing, but don’t have enough time to do? What things actually fill up your day? Are there things you could drop or minimize to make more time? We’ll look at some of these things in the following items, but it starts with taking a time out to think and plan.
2. Find your essentials. What is it that you love to do? Make a short list of 4-5 things. These are the things you want to make room for.
3. Find your time-wasters. What do you spend a lot of your time on that isn’t on your essential list? Take a close look at these things and really think about whether they’re necessary, or if there are ways to reduce, minimize or eliminate these things. Sometimes you do things because you assume they’re necessary, but if you give it some thought you can find ways to drop them from your life. Figure out what you do simply to waste time — maybe surfing certain sites, watching TV, talking a lot at the water cooler, etc. You’re going to want to minimize these time-wasters to make room for the more important stuff, the stuff that makes you happy and that you love to do.
4. Schedule the time. As you sit down and think about your life and what you want to do, versus what you actually do, you will be looking at ways to free up time. It’s crucial that you take a blank weekly schedule (you can just write it out on a piece of paper, or use your calendar) and assign blocks for the things you love — the stuff on your essentials list. If you want to exercise, for example, when will you do it? Put the blocks of time on your schedule, and make these blocks the most important appointments of your week. Schedule the rest of your life around these blocks.
5. Consolidate. There are many things you do, scattered throughout your day or your week, that you might be able to consolidate in order to save time. A good example is errands — instead of running one or two a day, do them all in one day to save time and gas. Another example is email, or any kind of communication — batch process your email instead of checking and reading and responding throughout the day. Same thing with meetings, paperwork, anything that you do regularly.
6. Cut out meetings. This isn’t possible for everyone, but in my experience meetings take up a lot of time to get across a little information, or to make easy decisions that could be made via email or phone. As much as you can, minimize the number of meetings you hold and attend. In some cases this might mean talking to your boss and telling her that you have other priorities, and asking to be excused. In other cases this might mean asking the people holding the meeting if you can get the info in other ways. If so, you’ve saved yourself an hour or so per meeting (sometimes more).
7. De clutter your schedule. If you have a heavily packed schedule, full of meetings and errands and tasks and projects and appointments, you’re going to want to weed it out so that it’s not so jam-packed. Find the stuff that’s not so essential and cancel them. Postpone other stuff. Leave big blank spaces in your schedule.
8. Re-think your routine. Often we get stuck in a routine that’s anything but what we really want our days to be like. Is there a better way of doing things? You’re the creator of your life — make a new routine that’s more pleasant, more optimal, more filled with things you love.
9. Cut back on email. I mentioned email in an earlier point above, regarding consolidating, but it’s such a major part of most people’s lives that it deserves special attention. How often do you check email? How much time do you spend composing emails? If you spend a major part of your work day on email, as many people do (and as I once did), you can free up a lot of time by reducing the time you spend in email. Now, this won’t work for everyone, but it can work for many people: choose 2-3 key times during the day to process your inbox to empty, and keep your responses to 5 sentences.
10. Learn to say no. If you say “yes” to every request, you will never have any free time. Get super protective about your time, and say “no” to everything but the essential requests.
11. Keep your list to 3. When you make out your daily to-do list, just list the three Most Important Tasks you want to accomplish today. Don’t make a laundry list of tasks, or you’ll fill up all your free time. By keeping your task list small, but populated only by important tasks, you ensure that you are getting the important stuff done but not overloading yourself.
12. Do your Biggest Rock first. Of the three Most Important Tasks you choose for the day, pick the biggest one, or the one you’re dreading most, and do that first. Otherwise you’ll put that off as much as possible and fill your day with less important things. Don’t allow yourself to check email until that Big Rock is taken care of. It starts your day with a sense of major accomplishment, and leaves you with a lot of free time the rest of the day, because the most important thing is already done.
13. Delegate. If you have subordinates or coworkers who can do a task or project, try to delegate it. Don’t feel like you need to do everything yourself. If necessary, spend a little time training the person to whom you’re delegating the task, but that little time spent training will pay off in a lot of time saved later. Delegating allows you to focus on the core tasks and projects you should be focusing on.
14. Cut out distractions. What is there around your workspace that distracts you from the task at hand? Sometimes it’s visual clutter, or papers lying around that call for your attention and action, or email or IM notifiers on your computer that pop up at the wrong time, or the phone, or coworkers. See if you can eliminate as many of these as possible — the more you can focus, the more effective you’ll be and the less time you’ll waste. That equals time saved for the good stuff.
15. Disconnect. The biggest of distractions, for most people, is the Internet. My most productive times are when I’m disconnected from the grid. Now, I’m not saying you need to be disconnected all the time, but if you really want to be able to effectively complete tasks, disconnect your Internet so you can really focus. Set certain times of the day for connectivity, and only connect during those periods.
16. Outsource. If you can’t delegate, see if you can outsource. With the Internet, we can connect with people from all over the world. I’ve outsourced many things, from small tasks to checking email to legal work to design and editing work and more. That allows me to focus on the things I’m best at, the things I love doing, and saves me a lot of time.
17. Make use of your mornings. I find that mornings are the absolute best times to schedule the things I really want to do. I run, read and write in the mornings — three of the four things on my Essentials List (spending time with family is the other thing on the list). Mornings are great because your day hasn’t been filled with a bunch of unscheduled, demanding, last-minute tasks that will push back those Essentials. For example, if you schedule something for late afternoon, by the time late afternoon rolls around, you might have a dozen other things newly added to your to-do list, and you’ll put off that late-afternoon Essential. Instead, schedule it for the morning, and it’ll rarely (if ever) get pushed back.
18. The Golden Right-after-work Time. Other than mornings, I find the time just after work to be an incredible time for doing Essential things. Exercise, for example, is great in the 5-o’clock hour, as is spending time with family, or doing anything else relaxing.
19. Your evenings. The time before you go to bed is also golden, as it exists every single day, and it’s usually completely yours to schedule. What do you want to do with this time? Read? Spend time with your kids? Work on a hobby you’re passionate about? Take advantage of this time.
20. Lunch breaks. If the three golden times mentioned above don’t work for you, lunch breaks are another good opportunity to schedule things. Some people like to exercise, or to take quiet times, during their lunch breaks. Others use this time to work on an important personal goal or project.
