Mindblow #87:


Kevin, from Vsauce2, has a new selection of science, tech and amazing stuff that needs to be shared all over the web. You can find out about augmented reality glasses, that lets you manipulate virtual objects by superimposing them over images from your surrounding.

You will then be able to play chess or Minecraft with your buddies in your own house.

Also, jetpack for runners. Never thought that such idea could be possible. It seems that such a small jetpack can help a runner run 1 mile in over 5 minutes and will help anyone run a mile in 4 minutes in the future.

You will find out about smart headlights right at the end of the video. Those headlights shoudl adapt to any condition and make sure they offer the best lighting for you and for other crossing your way. Neat, huh?

Learn about 5 ancient medical treatments with Vsauce2


Interestingly enough, medicine have come a long way since the days of the shamans or of bleeding as a practice to treat whatever ailment you’d have. Kevin from Vsauce2 shows us 5 ancient treatments they used back then and how were they performed.

Bleeding was one of those methods and it stuck with the then-day doctors up until the 19th century. Regular people or kings, all were bled to death according to astrology calenders. You may find with some surprise that this was a highly valued method as bleeding was seen as a purifying method widely accepted. You can read more about such methods in the book called An Underground Education: The Unauthorized and Outrageous Supplement to Everything You Thought You Knew out Art, Sex, Business, Crime, Science, Medicine, and Other Fields of Human by Richard Zachs. Great book, read it, love it.

Other old ways to treat illnesses were:
– trepanning – drilling a hole into the skull to let the evil spirits out
– enema – doing rectal purges using animal parts as tubes
– smoking – was used during the London plague
– smelling foul gases – during the London plague was used to ward off the plague as they believed that bad gases brought it in the first place.

The Polish have done it: they have created an IR invisible tank that also looks sleek and has a lot of automatic defense and offense modules. The PL-01 concept is a tank that relies heavily on new tech and senzors to outsmart the enemy. One of the coolest things is that it has an rocket auto-loader in the hull and that it’s armour does not let heat get out making it invisible to the IR detectors.

Also, the armour is absorbing radio signals, making it invisible to radio detectors. More details can be obtained about the tank in this YouTube description. Below is only a part of the description:
