Identify this invention which is widely used across the globe in its modernized avatar. (Hint: Think ancient)
77
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:

Google Googles:
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.
