இணையத்தில் உலா வந்த போது, சயின்ஸ் ஸ்நாக்ஸ் (Science Snacks) என்ற தலைப்பு சற்று வேடிக்கையாக என் கண்ணில் பட்டது. வியந்து உள்ளே சென்றேன். பின்னர் தான் தெரிந்தது, அங்கு உள்ள செய்திகள் மற்றும் தகவல்கள் அனைத்தும் மூளைக்கு தீனி (ஸ்நாக்ஸ்) போடும் அறிவியல் சமாச்சாரங்கள் என்று. அட, அப்படியா! என நாம் வியக்கும் வகையில், பல அறிவியல் விஷயங்களை இந்த இணைய தளம் நமக்குத் தருகிறது.
நாம் அன்றாடம் பார்க்கும் சில சாதாரண விஷயங்கள் குறித்து அவ்வளவாகச் சிந்திப்பதில்லை. ஆகாயம் ஏன் நீல நிறமாக இருக்கிறது? சூரியன் உதயம் மற்றும் அஸ்தமனம் ஏன் சிகப்பாக உள்ளது? பிளாஷ் லைட் எரிந்து அணைந்த பின்னர் அதன் இமேஜ் ஏன் நம் கண்கள் முன் தொடர்ந்து சில விநாடிகளுக்குத் தெரிகிறது? இரண்டு உதடுகளுக்கு இடையில் ஏன் சத்தம் வருகிறது? (இப்போது ஏன் உங்களுக்கு ஆர்வம் வருகிறது?)
இது போன்ற சாதாரண விஷயங்களுக்கு நாம் விளக்கங்களைத் தேடி எங்கு செல்வது? பல இணைய தளங்கள் இருந்தாலும், http://www.exploratorium.edu/snacks/index.html என்ற முகவரியில் உள்ள தளம், இந்த கேள்விகளுக்கு நல்ல விளக்கத்தினைத் தருகிறது. இது போன்ற பல விஷயங்கள் இதில் மிகவும் எளிமையாகவும், அனைத்து தகவல்களுடனும் தரப்பட்டுள்ளன.

India's leading engineering institute IIT Madras has a Healthcare Technology Innovation Centre (HTIC), a unit of the Research and Development, that has come up with a new affordable eye screening technology called 'Eye PAC' that helps ophthalmologists do their work faster. Up till now, patients with eye problems had to spend a whole day at the hospital for just the screening. With what they've developed here, the process takes just five minutes. Eye PAC is a software that extracts clear information from eyes and in turn help screen a large number of patients and send only the needy ones for further treatment. Thus, the eye doctor can focus on giving immediate diagnostic solutions.
HTIC unit's head Mr. Mohanasankar Sivaprakasam shared his concern by saying that "Over 80 per cent of cases of blindness in our country are preventable, if only there was no lack of qualified ophthalmologists." Therefore, using the Eye PAC technology what we essentially achieve is the bridging of gap of the shortage of ophthalmologists in the country.
The IIT's HTIC unit has worked on this project by collaborating with the Department of Biotechnology of Government of India. This project also supports '3nethra' -a low cost, portable, and highly integrated ophthalmology device for pre-screening and identification of potential eye diseases, developed by Bangalore-based med-tech firm Forus Health. 3nethra has been already installed in many locations across 10 countries such as India, China, France, Thailand, Sri Lanka, Nepal, Mauritius and Somalia. As we frequently read about the i-tech innovation across the world, in India we are seeing a lot of eye-tech innovation. Recently, we saw how four engineering students from Srinivas Institiute Of Technology, Mangalore came up with 'Eye Mouse' - a hands-free device that aims at letting the differently abled people use mouse on their computer screen in hands-free mode.
We look forward to more innovative solutions from India's leading technical institutes and organisations. What are your opinions? Share with us in comments.
WinRAR is a powerful archive manager. RAR files can usually compress content by 8 percent to 15 percent more than ZIP files can. WinRAR is a powerful compression tool with many integrated additional functions to help you organize your compressed archives. It can backup your data and reduce size of email attachments, decompress RAR, ZIP and other files downloaded from Internet and create new archives in RAR and ZIP file format.
WinRAR puts you ahead of the crowd when it comes to compression. By consistently creating smaller archives, WinRAR is often faster than the competition. This will save you disc space, transmission costs AND valuable working time as well. WinRAR is ideal for multimedia files. WinRAR automatically recognizes and selects the best compression method. The special compression algorithm compresses multimedia files, executables and object libraries
Features of WinRAR:
- Using WinRAR puts you ahead of the crowd when it comes to compression by consistently making smaller archives than the competition, saving disk space and transmission costs.
- WinRAR provides complete support for RAR and ZIP archives and is able to unpack CAB, ARJ, LZH, TAR, GZ, ACE, UUE, BZ2, JAR, ISO, 7Z, Z archives.
- WinRAR offers a graphic interactive interface utilizing mouse and menus as well as the command line interface.
- WinRAR is easier to use than many other archivers with the inclusion of a special "Wizard" mode which allows instant access to the basic archiving functions through a simple question and answer procedure. This avoids confusion in the early stages of use.
- WinRAR offers you the benefit of industry strength archive encryption using AES (Advanced Encryption Standard) with a key of 128 bits.
- WinRAR supports files and archives up to 8,589 billion gigabytes in size. The number of archived files is, for all practical purposes, unlimited.

Aakash 4 specifications & features list is ready and and the draft describing the same is soon to be submitted to the Government for approval. J Satyanarayana, secretar of Department of Electronics & IT informed the PTI. The government is already rolling up sleeves for the fourth generation of the Aakash tablet while the fate of Aakash 3 isn't clear yet. J Satyanarayana further said that the tablet specifications are beging finalised keeping the cost factor in mind. "We should not add so many features that the cost will go beyond", he said.
With that in mind, what can we expect in terms of hardware and software from Aakash 4? Let's try & make a guess based on the finalised specs for Aakash 3. Here's what we think would get featured in Aakash 4.
Unless Aakash 4 offers features what we've guessed, we believe the upgrade won't be worth it. It'd also be interesting to see which firmware does Aakash 4 will ship with. It's high time that the latest version of Jelly Bean Android finds its way to the tablet.
Aakash tablet was a brainchild of Kapil Sibal, who currently leads the law ministry in India. The idea was to provide a budget-friendly gadget to students in India so that they can have Internet access for educational purposes. The contract to design and develop the tablet was handed over to a Canadian company 'Datawind'. The first version of Aakash was rolled out in October 2011. The section generation was launched last year. We don't yet have concrete information on the status of Aakash 3 tablet.
When asked whether any private players have shown interest in manufacturing or assembling the tablet in India, Satyanarayana said that no company has come forth yet, but once the specifications are finalised, proposals would come in.
We'd love to hear reviews and feedback about Aakash tablet from oure readers & members. Chinese computer giant Lenovo had backed out from submitting proposals stating that it was almost impossible to offer a better user experience in the price bracket set by the Government. Do Aakash owners think that the tablet offers value for money? Share your opinion with us through comments.
