Pay with your hand using vein scanning

Paying for a coffee or lunch by simply scanning your palm still sounds like science fiction to most of us. However, an engineering student at Lund University in Sweden has made it happen - making his the first known company in the world to install the vein scanning technique in stores and coffee shops.

This is Your Brain on Engineering

This Easter, we wanted to highlight some of the reasons more choices for girls are so important. Why stay on a conveyor belt when you can build your own Ferris wheel, after all?

We’re GoldieBlox, a toy company out to show the world that girls deserve more choices than dolls and princesses. We believe that femininity is strong and girls will build the future — literally.

Our founder, Debbie Sterling, is a Stanford engineer who decided that girls need more choices than the pink aisle has to offer. She developed GoldieBlox, an interactive book series + construction set starring Goldie, the kid inventor who loves to build.

Nerdy Engineer: Neil Armstrong on Being a Nerd

Light Speed: From Minecraft to Reality [Science!]

Science and videogames! Together!

Minecraft can be a great tool for visualizing complicated subjects, such as the speed of light (aka “c”). Using a straight track and simple math, we can see how the universe might be limiting speeds for very fast things, such as light.

The “doors” metaphor is admittedly, imperfect. While they do limit speed outside of “acceleration”, they falsely imply that there is something “in space” that slows things down, which does not appear to be the case at the moment. The actual mechanisms that limit objects to light speed will be the topic for a future video. (Hint: It has to do with time!)
