28 फरवरी : जानिए आज के दिन क्यों मनाया जाता है राष्ट्रीय विज्ञान दिवस


राष्ट्रीय विज्ञान दिवस

28 फरवरी को देश में विज्ञान दिवस के रूप में मनाया जाता है। यही वह दिन है जब देश के महान वैज्ञानिक सीवी रमन ने ‘रमन प्रभाव’ का आविष्कार किया था, जिसके लिए उन्हें नोबेल पुरस्कार से सम्मानित किया गया।
महान भौतिक विज्ञानी सर चंद्रशेखर वेंकट रमन ने 28 फरवरी 1928 को भौतिकी के गंभीर विषय में एक महत्वपूर्ण खोज की थी। पारदर्शी पदार्थ से गुजरने पर प्रकाश की किरणों में आने वाले बदलाव पर की गई इस महत्वपूर्ण खोज के लिए 1930 में उन्हें भौतिकी के नोबेल पुरस्कार से सम्मानित किया गया।वह यह पुरस्कार ग्रहण करने वाले भारत ही नहीं बल्कि एशिया के पहले वैज्ञानिक थे।

इस खोज के सम्मान में 1986 से इस दिन को राष्ट्रीय विज्ञान दिवस के रूप में मनाने का चलन है। 1954 में भारत सरकार ने उन्हें सर्वोच्च नागरिक सम्मान भारत रत्न से नवाजा। राष्ट्रीय विज्ञान दिवस 2020 की थीम 'Women in Science' है।
राष्ट्रीय विज्ञान दिवस मनाने का ये हैं मूल उद्देश्य
इस दिवस का मूल उद्देश्य विद्यार्थियों को विज्ञान के क्षेत्र में नए प्रयोगों के लिए प्रेरित करना, विज्ञान के प्रति आकर्षित करना, तथा विज्ञान एवं वैज्ञानिक उपलब्धियों के प्रति सजग बनाना है।

इस दिन, विज्ञान संस्थान, प्रयोगशाला, विज्ञान अकादमी, स्कूल, कॉलेज तथा प्रशिक्षण संस्थानों में वैज्ञानिक गतिविधियों से संबंधित प्रोग्रामों का आयोजन किया जाता हैं। रसायनों की आणविक संरचना के अध्ययन में 'रमन प्रभाव' एक प्रभावी साधन है।

राष्ट्रीय विज्ञान दिवस देश में विज्ञान के निरंतर उन्नति का आह्वान करता है, परमाणु ऊर्जा को लेकर लोगों के मन में कायम भ्रांतियों को दूर करना इसका मुख्य उद्देश्य है तथा इसके विकास के द्वारा ही हम समाज के लोगों का जीवन स्तर अधिक से अधिक खुशहाल बना सकते हैं।
कौने थे सर सीवी रमन
सर सी.वी रमन का जन्म ब्रिटिश भारत में तत्कालीन मद्रास प्रेसीडेंसी (तमिलनाडु) में सात नवंबर 1888 को हुआ था। उनके पिता गणित और भौतिकी के प्राध्यापक थे। सीवी रमन ने तत्कालीन मद्रास के प्रेसीडेन्सी कॉलेज से बीए किया और इसी कॉलेज में उन्होंने एमए में प्रवेश लिया और मुख्य विषय भौतिकी को चुना।

जब विज्ञान के क्षेत्र में आगे बढ़ने की सुविधा नहीं मिलने के कारण सीवी रमन ने सरकारी नौकरी का रुख किया था। उन्होंने भारत सरकार के वित्त विभाग की प्रतियोगिता परीक्षा में भाग लिया और उन्हें प्रथम स्थान मिला।

इसके बाद उन्होंने कोलकाता में 1907 में असिस्टेंट अकाउटेंट जनरल की नौकरी की लेकिन विज्ञान के प्रति उनका लगाव होने के कारण यहां वह इंडियन एशोसिएशन फार कल्टीवेशन आफ साइंस और कलकत्ता विश्वविद्यालय की प्रयोगशालाओं में शोध करते रहे।
सर सीवी रमन के मुख्य आविष्कार
भौतिक शास्त्री सर सीवी रमन सिर्फ भारतीयों के लिए बल्कि दुनिया भर के लोगों के लिए प्रेरणास्रोत हैं। इन्होंने स्टील की स्पेक्ट्रम प्रकृति, स्टील डाइनेमिक्स के बुनियादी मुद्दे, हीरे की संरचना और गुणों और अनेक रंगदीप्त पदार्थो के प्रकाशीय आचरण पर भी शोध किया। उन्होंने ही पहली बार तबले और मृदंगम के संनादी (हार्मोनिक) की प्रकृति की खोज की थी।

World book night Column- Piyush Jha talks about a new way to celebrate reading and books




While surfing the net on the first days of the new year, I stumbled upon something that I had never heard of before - World Book Night! It turns out that intrepid bibliophiles have been at work expanding the scope for books and reading. Apparently, the event is celebrated for almost 10 years now on the same date as the UNESCO International Day of the Book- 23rd April. Since World Book Day is a well-established reading celebration for children during the day, World Book Night is for grown-ups to celebrate books in different ways at night.

April is still some time away, but I’m just putting the idea out there for people to use and get inspired. For those that need some help in the planning, World Book Night also has a website that you can connect with to figure out ideas that you can use to have your own little celebration. They also have helpful categories and appropriate activities. For instance, as an individual, you could simply hold book swaps with friends and colleagues or if you’re adventurous and outgoing, you could even have a full-fledged book-themed party. Writers and readers could have a small reading with at their favourite cafe or go live on social media using #worldbooknight. Bookstores are encouraged to have Author visits and special offers and discounts on the said night. Waterstones bookstore in Doncaster in the UK quite successfully motivated their regular patrons to buy a book and share it with someone who would not have discovered it otherwise. Libraries could create a special World Book Night list which they can share with their members for their night-time read. Organisational workplaces are urged to present books to employees who otherwise might not be reading or are lapsed readers. There are even suggestions to celebrate World Book Night with care homes, old age homes, orphanages and other NGOs.

It’s commendable, the lengths to which The Reading Agency, the organisation behind World Book Night has gone to make the event a meaningful activity. Currently, the event is celebrated in the UK and the US, but I’m pretty sure that we in India can make a bid to participate, in at least our major cities.

Since, 23rd April also happens to be the probable birth and death date of William Shakespeare, I’m sure he’d approve saying, “A beggars book, outworths a noble’s blood.”

Future classroom: How tech is changing the way we learn

education sector in 2020, 5G smartphones, Artificial intelligence, B2B tech deployments, Global solutions, 3D printing,  CAD/CAM


Whoa! It’s almost 20 years since the new millennium, and the generation that was born then is already in universities. This new generation has spent its teenage days surrounded by technology. Let us then have a look at how technology is shaping the education sector, and what the top trends of 2020 are going to be:

1. Impact of 5G smartphones: With the launch of 5G smartphones, teachers and students will soon have a mobile internet connection that is faster than the one they access via their institutes. It can lead to a rise in school infrastructure spending.

2. Artificial intelligence: AI is helping enhance the learning curve of students and teachers. For instance, by coupling it with video analytics, AI can detect responsiveness of a class as well as a student. It can inform a teacher about weak engagement points and support skill building. This progression will continue in 2020.

3. Content experience: Building on the concept of smart classes, will AR and VR step into the picture across schools and colleges? This depends on the scale and forward-looking vision of an institute. If you are a large institute, there are more opportunities to use AR/VR kits; smaller schools may struggle to find economies of scale, and can eye rental solutions.

4. Procurement: Alternative corporate finance mechanisms are in place with schools to drive edtech procurements via subscription contracts that enable flexibility, support and maintenance. Such initiatives can also be evidence-based, and if the technology procured isn’t as supportive as marketed, the school can give it back.

5. Workforce reform: Towards the end of 2020, it is hoped schools will start to enjoy the fruits of their initial challenges, including workforce-related reforms.

6. Edtech and supplier partnerships: The advent of tech players has changed the nature of B2B tech deployments within the industry. Educational institutes are now barely treated as a customer, but more like equal partners. We might see a greater emphasis on this front in 2020.

7. Global solutions: Solutions to economically deliver content to students at scale are being launched in India and the world. Tech is paving the way for the global integration of our education system.

8. Devices: All devices can more or less run any software these days, as everything is shifting to the cloud. So, it comes back to budget, especially considering the number of devices needed across schools and the capabilities they may need to run specific applications such as graphics, video editing. CAD/CAM and 3D printing are becoming cheaper to purchase and run. It will help younger generation to expand its scope of work with on-the-go applications.

9. Connected classrooms: It will help in better resource optimisation as a single teacher will be able to communicate with multiple classrooms at once—help extend first-rate education to everyone without depending on the teacher-to-pupil ratio.

10. Futuristic classroom: We return to the cliché—will we see changes in how classrooms are traditionally set up? We have seen more open-plan environments emerging all over the world. This also holds true for India as we see new schools being designed using unconventional approach. We might start to see specialist classrooms with both teachers and students moving around more freely … or maybe not.

Govt. launches road accident database

Pilot project in six States will be followed by pan-India roll out
The government on Monday launched a central accident database management system that will help in analysing causes of road crashes and in devising safety interventions to reduce such accidents in the country.

The IT tool, known as the Integrated Road Accident Database (IRAD), has been developed by the Indian Institute of Technology-Madras (IIT-M) and will be implemented by the National Informatics Centre. The project costs ₹258 crore and is being supported by the World Bank.

Highest fatalities
The system will be first piloted in the six States with highest fatalities from road crashes — Karnataka, Madhya Pradesh, Maharashtra, Rajasthan, Tamil Nadu and Uttar Pradesh. The IRAD will be improved on the basis of the learnings from the trial, following which it will be rolled out across the country.

Defence Minister Rajnath Singh and Union Minister for Road Transport and Highways Nitin Gadkari inaugurated the IRAD at the road safety stakeholders’ meet. Mr. Gadkari said that around 30,000 tablets would be distributed to police personnel across the country to record data on accidents.


How it works
The IRAD mobile application will enable police personnel to enter details about a road accident, along with photos and videos, following which a unique ID will be created for the incident. Subsequently, an engineer from the Public Works Department or the local body will receive an alert on his mobile device. He or she will then visit the accident site, examine it, and feed the required details, such as the road design. Data thus collected will be analysed by a team at IIT-M, which will then suggest if corrective measures in road design need to be taken.

Road users will also be able to upload data on road accidents on a separate mobile application, which is expected to go live from April 1, according to a Ministry official.

Overspeeding
India sees the largest number of road fatalities in the world. More than 1.5 lakh people lost their lives in road crashes in the country in 2018, according to government data. Of the total people killed in road crashes in 2018, 48% were between 18 years and 35 years old, and more than 60% of such fatalities were due to overspeeding.
