Finding space objects

The headline is a little misleading. The story is that this high schooler did some summer work at cal tech. He saw a database full of information and wrote some fairly simple code to parse through it based on what we know. 

He used the notion that many objects will have a heat signature that would have been captured along the way and be in that database. 

The code picked out those objects and found literally millions of objects that would have been otherwise missed in that data.  

It's very, very cool. And yes there is an element of "machine learning" because the code adapted a bit as it found objects and information that would be valuable.

An alternative to traditional air conditioning.

A team of scientists in Hong Kong have come up with a heat exchange system that can be used in place of a traditional air conditioner. It's more energy conscious, is less costly, and doesn't use any chemicals (like Freon or Freon alternatives) to function. 

It's fairly simple in that it just removes the heat through a series of tubes and replaces that with cooler air. 

Its a nice leap forward.

Wireless electricity

This is a broad overview of wireless electricity, its development, and some practical real-world applications. 

The article also notes that Nikola Tesla proposed this idea in the early 1900s and had been toying with it a bit. But the technology wasn't quite there, and the transmission of power was a huge business, so companies didn't want this. 

As a professional engineer this pisses me off

The state of Florida wants to abolish the board of professional engineers and roll its function under the department of professional regulation - where they have no understanding of engineering. 

We are in the public trust and have to hold to a standard. They want to eliminate that standard. 

And why might they be doing this? At least in part as a favor to the insurance industry. PEs are often utilized in legal actions involving them - and they always contradict it with their own experts. With no regulatory board, the insurance company gets a big advantage.

Canadian MP Charlie Angus on T-rump

Oh yeah, he calls out the orange menace for being the absolute fool he is, and how Canadian citizens have come together.
