The first beneficiaries of quantum computing?

Chemists. Who’d a thunk that one. It’s not totally there yet, but quantum chemistry may transform the field.

From the link:

There’s no shortage of scientists waiting to get their hands on quantum computers. Cryptographers, in particular, are licking their lips in anticipation.

But there’s another group who are already beginning to benefit from the first few iterations of quantum computing devices: chemists.

Various scientists have pointed out that it is possible to study the properties of a particular quantum system using another controllable quantum system.

This kind of quantum simulation has huge implications for chemistry. No longer would it be necessary to mess around with real atoms, ions and molecules in messy experiments with test tubes and bunsen burners.

Instead it ought to be possible to perfectly simulate what goes on using a quantum computer set up in the right way. That’s the theory anyway. The practice is inevitably more tricky.

Get a free online education with Khan Academy

I came across this post at Metamodern discussing a very interesting, and utile, online resource — Khan Academy. If you’re looking for short, to-the-point online lessons (more than 1000) on mathematics ranging from basic arithmetic and algebra to differential equations, physics, chemistry, biology and finance, this is a great resource.

From the first link:

I got a pointer to a free, online educational resource today.

It deserves more attention.

The eyeballs of a few million students might be a good start. Students in elementary school, grad school, rural Africa… places like that.

It consists of 1000+ brief lectures on YouTube.

It centers on math, but goes beyond.
