Identify this invention which is widely used across the globe in its modernized avatar. (Hint: Think ancient)
Ans.: Vending Machine. The first recorded reference to a vending machine is found in the work of Hero of Alexandria, a first-century engineer and mathematician. His machine accepted a coin and then dispensed a fixed amount of holy water. When the coin was deposited, it fell upon a pan attached to a lever. The lever opened up a valve which let some water flow out. The pan continued to tilt with the weight of the coin until it fell off, at which point a counter-weight would snap the lever back up and turn off the valve.

Caught a fleeting glimpse of this white drifter and couldnt help but to rush to the window to see what it was? I am happy to share it here:
Science Express is a unique science exhibition on a 16-coach, fully AC train, traveling across India. This exhibition showcases cutting-edge research in Science. An Indo-German collaborative project; it was flagged off on 30 October 2007 by Honorable Prime Minister of India Dr. Manmohan Singh and German Chancellor Dr. Angela Merkel. This innovative exhibition has received an unprecedented response and created four National Records. During its three phases, till April 2010, it has been visited by over 51 lakh people, mostly students. So far, it has traveled over 50,000 km, covering 150 locations, during its 600 exhibition days.
This state-of-the-art mobile exhibition attempts to develop scientific temper amongst the masses and encourages students to pursue higher studies and careers in science. It hosts interactive exhibits developed by Max Planck Society, Germany; Department of Science & Technology (DST), Govt. of India and Vikram A Sarabhai Community Science Centre (VASCSC), Ahmedabad.

Google Goggles lets you use pictures taken with your mobile phone to search the web. It’s ideal for things that aren’t easy to describe in words. There’s no need to type or speak your query – all you have to do is open the app, snap a picture, and wait for your search results.
Google Goggles works better with certain types of queries. Try taking pictures of books & DVDs, landmarks, barcodes & QR codes, logos, contact info, artwork, businesses, products, or text; it can recognize up to three items at a time. Currently, it’s not so good when taking pictures of animals, plants, cars, furniture, or apparel.
For the best results when taking pictures, hold your phone in “left landscape” mode, as shown below, and press the on-screen shutter button with your right thumb.
