Science: CubeSat Propulsion, Smart Roads

The Future of CubeSat Propulsion

SciShow Space – Oct 1, 2019
CubeSats have a lot of advantages, but they need a way to move and still stay small, and that means new miniaturized propulsion systems that can help us get these tiny spacecraft out into the universe.

These Smart Roads Could Change the Future of Driving

SciShow – Sep 30, 2019
From self-healing asphalt to electrified roads, technology is steering the future of driving along some exciting new paths!

Speaking of the future of driving, here’s Mindful Webworks’ take on the future of transportation, from June, 2013, 30 panels like this first one:

Feeding the Cats, Feeding the Dog

Responses Comparative Study

Feeding the cat

Track the cat down, they don’t come when called.

Sometimes they don’t even react when I wave the bowl in front of them.

Watch them saunter up to the bowl sloooowwwly.

They might sniff at the food, look up and mew, like, wtf is this? (Same thing you always get, kitty!)

Sometimes even turn away without eating. (Oh, have you already eaten someone this morning?)

They tend to leave a little bit uneaten.

Then they wander off and clean themselves.

Sleepy Dog and Cat

Feeding the dog

He’s right there on time, or runs to me when called.

As I approach with the food bowl, he dances with delight. He’ll wiggle and walk backwards and shake like a puppy. Funny to see in an old dog. It’s a great reward for me.

When I set the bowl down – I love this ritual – no matter how late feeding may be, or how hungry he might be, the dog pauses, looks up at me, so I can pet him and say, “good dog,” and then he chows down with enthusiasm.

His face doesn’t come out of the bowl until it’s clean.

Then he comes to me for more pets.

However, he isn’t a very good mouser.
