Hold the mouth of a black trash bag in one hand. Use a hair dryer to blow hot air into the bag. Seal the mouth of the bag with tape. Tie a long piece of string
around the tape so you can hold it. Take the bag out into the sun. The
bag will rise slowly into the air. (It’s best to do this trick in an
open area on a windless day.)How Does It Work? Since the bag is black, it absorbs heat from the sun. That heat makes
the air inside the bag expand and become lighter. When the bag and the
air inside are lighter than the surrounding air, the bag starts to rise. =================================================================== एक उड़ती कूड़े की थैली एक हाथ में एक काले कचरा बैग का मुंह पकड़ो बैग में गर्म हवा को उड़ाने के लिए हेयर ड्रायर का उपयोग करें टेप के साथ बैग के मुंह को सील करें टेप के चारों ओर एक लंबा टुकड़ा लगाया ताकि आप उसे पकड़ सकें। बैग को सूरज में ले जाओ बैग धीरे-धीरे हवा में बढ़ेगा (दिन के बिना हवा में खुले क्षेत्र में यह चाल करना सबसे अच्छा है।)
यह कैसे काम करता है? क्योंकि बैग काला है, यह सूर्य से गर्मी को अवशोषित करता है। उस गर्मी से बैग के अंदर हवा का विस्तार हो जाता है और हल्का हो जाता है।जब बैग और हवा के अंदर की हवा की तुलना में हल्का होते हैं, तो बैग बढ़ने लगती है।

घर की सामग्री से 3D Hololens बनाइये What Is The HOLOLENS.
HoloLens is essentially a holographic computer built into a headset that lets you see, hear, and interact with holograms within an environment such as a living room or an office space. Microsoft has built the headset without the need to be wirelessly connected to a PC, and has used high-definition lenses and spatial sound technology to create that immersive, interactive holographic experience.The HoloLens comes with semitransparent holographic lenses which ‘generate multi-dimensional full-colour holograms’. That means it’s not going to be projecting images into a room that everyone can see. It’s cutting edge stuff, but it’s not quite that advanced yet. In much the same way as Google’s ill-fated Glass experiment, the HoloLens will interject virtual elements onto your vision. That means it’s different to virtual reality headsets such as the HTC Vive, Oculus Rift, and Playstation VR. These VR headsets immerse you in a fully simulated world, whereas the HoloLens uses the real world as a canvas on which to overlay virtual elements.
(होलोलेन्स क्या है? HoloLens अनिवार्य रूप से एक होलोग्राफिक कंप्यूटर हैडसेट में बनाया गया है जिससे आपको एक ऐसे वातावरण के भीतर होलोग्राम देखने, सुनना और इंटरैक्ट करने की सुविधा मिलती है जैसे कि एक लिविंग रूम या ऑफिस स्पेस। माइक्रोसॉफ्ट ने हेडसेट को बिना किसी पीसी से जुड़े रहने की आवश्यकता के बिना बनाया है, और उस इमर्सिव, इंटरेक्टिव होलोग्राफिक अनुभव को बनाने के लिए हाई डेफिनिशन लेंस और स्पेसिअल साउंड टेक्नोलॉजी का इस्तेमाल किया है। होलोलेंस semitransparent होलोग्राफिक लेंस के साथ आता है जो 'बहु-आयामी पूर्ण रंग वाले होलोग्राम उत्पन्न करते हैं' इसका अर्थ यह है कि वह एक कमरे में छवियां पेश करने वाला नहीं है जो सभी देख सकें। यह बढ़त सामान काट रहा है, लेकिन यह अभी तक उन्नत नहीं है। Google के दुर्दम्य ग्लास प्रयोग के समान, उसी तरह, होलोलेंस आपके दृष्टिकोण पर आभासी तत्वों को आक्षेप करेगा। इसका अर्थ यह है कि आभासी वास्तविकता हेडसेट जैसे कि एचटीसी विवे, ओकुलस रिफ्ट, और प्लेस्टेशन वीआर जैसी भिन्नताएं हैं। ये वीआर हेडसेट्स पूरी तरह सिम्युलेटेड दुनिया में विसर्जित करते हैं, जबकि होलोलेंस असली दुनिया का प्रयोग ऐसे कैनवास के रूप में करता है जिस पर आभासी तत्वों को ओवरले करना है)
How to Make A HOLOLENS
The idea for the Cardboard Hololens is simple. Its design inspiration comes from google cardboard VR. Just like cardboard it uses your phone to display steroscopic images to simulate 3D content. But instead the phone is placed above your eyes and then the images are then reflected via semi reflective/ transparent glass into your field of view. This way the 3d content is mixed with the real world at a fixed depth. (कार्डबोर्ड होलोलेंस का विचार सरल है इसकी डिजाइन प्रेरणा Google कार्डबोर्ड वीआर से आता है।कार्डबोर्ड की तरह ही यह आपके फोन का इस्तेमाल 3D सामग्री के अनुकरण के लिए स्टेरोस्कोपिक छवियों को प्रदर्शित करने के लिए करता है।लेकिन
इसके बजाय फोन को आपकी आंखों के ऊपर रखा गया है और फिर छवियां तब आपके
क्षेत्र को देखने के लिए अर्ध रिफ्लेक्टिव / पारदर्शी ग्लास के माध्यम से
परिलक्षित होती हैं।इस तरह से 3 डी सामग्री को एक निश्चित गहराई पर वास्तविक दुनिया के साथ मिश्रित किया जाता है।) Now the actual display technology behind the Hololens is far more advanced but, this is a work in progress, first build prototype. (अब होलोलेंस के पीछे वास्तविक डिस्प्ले टेक्नोलॉजी बहुत अधिक उन्नत है, लेकिन यह काम प्रगति पर है, पहले प्रोटोटाइप का निर्माण करें।)

Step 2: Measurement & Cutting (माप और कटाई)
Measurement of Card Board (कार्ड बोर्ड शीट का नाप)
Next use an box cutter to precisely cut up the cardboard into 5 pieces. Essentially we are going to be building a rectangular box. The length and width of the pieces should be based around the screen size of YOUR phone. The height of pieces depends on the focal length of the lens. For the smartphone which screen size 5.5 inches I found these measurements to be most effective. (अगले 5 टुकड़ों में कार्डबोर्ड को ठीक करने के लिए बॉक्स कटर का इस्तेमाल करें।मूल रूप से हम एक आयताकार बॉक्स का निर्माण करने जा रहे हैं।टुकड़ों की लंबाई और चौड़ाई आपके फोन के स्क्रीन आकार के आस-पास होनी चाहिए।टुकड़ों की ऊंचाई लेंस की फोकल लंबाई पर निर्भर करती हैस्मार्टफ़ोन के लिए जो कि 5.5 इंच स्क्रीन आकार की थी, मैंने इन मापों को सबसे प्रभावी माना।)
Then Black Tape Wrap Around The Card Board Sheet And Wrap it Like This (कटिंग के बाद काली टेप को कार्ड बोर्ड शीट के चारो और इस प्रकार से लपेटे )
Cut 2 holes in the base piece of your cardboard cut. The distance between the two holes should be 1inch.
I also cut out a long piece of cardboard and bent it in 2 places. This is optional but it can be used as a fastener to hold your phone in place so you won't have to hold it with your hands. We will need 2 pieces of Velcro to accomplish this: one on the fastener and one on the box frame
Next wrap all your pieces in electric tape to get a smooth finish. The black color of the tape will help keep in the light. I also used the tape to attache the fastener to the side of the cardboard piece.
अपने कार्डबोर्ड कट के आधार टुकड़े में 2 छेद कट करें।दो छेद के बीच की दूरी 1 इंच होनी चाहिए।। मैंने भी कार्डबोर्ड का एक लंबा टुकड़ा कट कर इसे 2 स्थानों पर झुका दिया।यह
वैकल्पिक है लेकिन इसका उपयोग आपके फ़ोन को जगह रखने के लिए एक फास्टनर के
रूप में किया जा सकता है ताकि आपको इसे अपने हाथों से नहीं पकड़ना पड़े।इसे पूरा करने के लिए हमें 2 के व्ल्क्रो की आवश्यकता होगी: फास्टनर पर और बॉक्स फ्रेम पर एक. एक चिकनी खत्म करने के लिए अगले टेप को अपने सभी टेपों को इलेक्ट्रिक टेप में लपेटें।टेप का काली रंग प्रकाश में रखने में मदद करेगामैंने टेपर का इस्तेमाल कार्बोस्टर टुकड़ा के किनारे फास्टनर को अटैच करने के लिए भी किया था.
Step 3: After Assemble of Frame (फ्रेम के इकट्ठा करने के बाद)
01 Front Side 02 Back Side
Carefully tape the pieces together to form a rectangular box. As you can see it resembles google cardboard. Insert the lens into the box as shown above. The fastener should function to wraparound the top opening of the box so it will secure the phone. I used a hot glue on the velcro strips as shown above. (एक आयताकार बॉक्स बनाने के लिए टुकड़ों को एक साथ चिपकाएं।जैसा कि आप इसे Google कार्डबोर्ड के जैसा देख सकते हैं. ऊपर दिखाए गए अनुसार बॉक्स में लेंस डालें।फास्टनर को बॉक्स के शीर्ष खोलने को लपेटने के लिए कार्य करना चाहिए ताकि वह फोन सुरक्षित करे।मैंने ऊपर दिखाए अनुसार वेल्क्रो स्ट्रिप्स पर एक गर्म गोंद का इस्तेमाल किया)
Step 4: Assemble Glass ( इकट्ठा ग्लास )
Next your are going to cut out reflective material into pieces as shown in the top left photo. Assemble the pieces using clear scotch tape to form a visor like design as shown in the pictures. Use electric tape to tape the visor to the cardboard frame as shown to ensure a rigid structure .The long piece of reflective glass should be angled at 45 degrees in-front of your eyes so that the glass touches your.( इसके बाद आप पारदर्शी कांच को टुकड़ों में काट लेंगे जैसा कि दिखाया गया है चित्रों में दिखाए गए अनुसार डिज़ाइन की तरह एक टोपी का छज्जा बनाने के लिए स्पष्ट स्कॉच टेप का उपयोग करके टुकड़ों को इकट्ठा करेंकठोर संरचना को सुनिश्चित करने के लिए दिखाए गए अनुसार कार्डबोर्ड फ़्रेम में टोपी का छज्जा टेप करने के लिए बिजली टेप का उपयोग करेंचिंतनशील ग्लास का लंबा टुकड़ा अपनी आँखों के सामने 45 डिग्री पर गुना होना चाहिए ताकि पारदर्शी कांच आपकी नाक को छू सके।)

स्मार्ट फ़ोन के साथ
Now run the 3D test scene. Rotate your phone landscape. Turn your screen brightness all the way up. Open the fastener and lay your screen horizontal aligned with the lens. The box is meant to be held with the box above your eyebrows and the glass in front of you eyes. Look through the glass reflector. Once you see the solar system in your field of vision it might need to be adjusted if it appears double imaged. Once correctly aligned the solar system will appear to have 3d stero depth. Once correct close and velcro the fastener.

ABOUT DEVELOPMENT COUNTRY The role of technology in the economic progress of a nation is well
recognized and appreciated, efforts are being made globally to develop
technology strengths and make the industries competitive, for
well-rounded development of the society. The developing countries
specially have shown a marked rise in the pace of economic growth in
recent years with focus on Science, Technology & Innovations. If
the trends available are to be believed, there is likely to be a shift
in economic power towards the third world countries in the 21st century.
Changes
in the global economic scenario, growing aspirations of Indian
population for better living and the fact that India would be a
developed nation by 2035, have challenged TIFAC to delineate a Vision
for the country. Having commended Technology Vision 2020 in the 1990s
to catapult India into the league of developed countries, TIFAC has now
geared-up itself to deliver Technology Vision 2035 for India.
Logistics and transport VISION 2035
The past 25 years have seen some huge changes, brought on by many forces including political, environmental, technological, social and demographic. These forces are continual and will shape the next 25 years, with considerable impact on the way we travel and transport goods.
help steer our vision towards a future that is better not just for transport and logistics but also for society too.
To understand the scale of change that could take place by 2035, just look back at what has changed over the past 25 years. In those days there was no internet, we were road building (completing the M25), almost nobody had a mobile phone and environmental concerns were not widespread. Transport facilities such as journey planning and ticketing were nowhere near as sophisticated as they are today. What will the next 25 years hold, and what challenges and pressures will emerge to shape the way transport systems evolve?
The forces There are strongDemographic forces, such as a rising and ageing population and persisting inequality. There will be a large shortfall of homes in the UK by 2035 and concerns as to where this housing will be located. The impact of transport forces is uncertain. Is demand stabilizing or will it still be increasing in the future? Public transport travel is certainly rising although today we are seeing only a minimal rise in car travel. The cost of travel is generally increasing in real terms. Prospects vary for domestic and international air travel. Economic forces- are significant, with the performance of the economy key to future activity. There is likely to be slow growth in the short term but stronger growth by 2035. Environmental costs will be increasingly reflected in the costs of goods and services. Road congestion costs are high and may become severe. We are increasingly aware of environmental forces such as climate change and other transport emissions. Political forces- suggest the likelihood of a changing role for government as it emerges in new regional bodies. There is a changing balance of power, with the private sector providing increasing levels of funding and multinational corporations becoming more influential in terms of both investment and policy. New partnership models are emerging and the voluntary sector is being called upon increasingly. The ‘user pays’ principle is becoming enshrined in government thinking, which could steer the government towards road user charging in time. There is an international context here whereby supply chains will potentially be impacted by factors in the developing world, including the expansion of Chinese influence, conflict zones and natural disasters. Finally there are Technological forces that have taken off in the last few decades, and look set to continue in such a fashion. Electric cars, alternative fuels, information technology and ticketing provision are likely to push forward rapidly in the next 25 years. These changes all have implications for the logistics and transport sector. Together the forces show some clear directions in which transport and logistics policy and service provision should evolve. Not just in national freight and passenger networks, but in the environmental arena too, in organizational arrangements, information provision, collective mobility, advanced technology and in training. Implications for the logistics and transport sector
In freight transport we will see increasing agility and flexibility in the supply chain by 2035. But domestic pressures, not least growing levels of congestion, and international forces will have a direct influence on tomorrow’s answers. These include sharing data, standardising business processes, pooling vehicle and warehouse capacity, automated warehousing, and collaborative partnerships. Freight will use new technologies to supply customers. It will also need an improved partnership with government. The implications for national passenger networks include making provision for the rising - and ageing - population, by increasing capacity via projects such as High Speed 2 (HS2) betweenLondon, Birmingham and the north as well as other committed schemes such as Crossrail. This is not restricted to rail. Bus and coach networks will also need to expand. Integration between operators and modes must be fostered by adopting approaches based on collective mobility (which includes local rail, bus and tram services, community transport, taxis, lift-sharing and car clubs). The challenge will be to integrate services that are in separate ownership and without restricting competition. The financial burdens on the UK limit its ability to fund new infrastructure over the next decade, and behavior change that encourages the use of more sustainable modes could help fill the gap. Road user charging is another possible tool. The Whole world contribution to reducing CO2 via the transport sector should be a high priority objective
Twenty-five years ago 01. To understand the scale of the change that could take place by 2035, it is worth looking back over the past 25 years to 1986. Whatever vision is proposed, one thing is certain – reality will turn out to be different, and in all likelihood, more radical than anything we can imagine at present. 02. This is brought home by reflecting on some major differences in transport and society 25 years ago. For example, the internet had yet to be created and the first generation of ‘brick’ mobile phones was being tested. The vehicle tracking systems that enable real time information were in their infancy and the ability to plan journeys in advance by checking on live travel conditions and buying tickets via a mobile phone would have appeared far-fetched. Smart card ticketing was nearly two decades away in the UK, and cars were largely without the in-vehicle entertainment and guidance systems that are a feature of road travel today. Transport policy was radically different too. In 1986, challenges to predict and provide were only just starting to gather momentum and large road building programmes were still seen by government as the way to cater for travel demand. 03 Organisationally, the state still operated almost all passenger transport services in 1986. The bus industry was just being privatised, and deregulated outside London. Rail privatisation was nearly a decade away, as was the creation of the Highways Agency. Fourteen years after the abolition of the Greater London Council, the Greater London Authority was created with significant devolved powers. This led in 2003 to the introduction of the UK’s first major congestion charging scheme. Now I Show You A Glimpses of The Future
