Someone did the math

Question:

What if every cat in the world surrounded you and meowed at the same time? How loud would it be?

Answer:

[…] it would be about 97dB. That’s something like the sound of a loud motorcycle passing right by you. Not deafening, but uncomfortably loud.

Interestingly you don’t even need all the cats in the world. After about 10,000 cats, they start getting too far away to matter.

How to study based on how memory works

Remember GOAT ME:

  • G is generate and test. Quiz yourself and teach others.
  • O is organize. Organize with outlines, pictures, color coding, related material, etc.
  • A is avoid illusions of learning. Avoid study methods that rely on recognition. If you can’t remember it at any given time, you don’t know it. Learn, not memorize or familiarize.
  • T is take breaks. Make sure you take breaks and get enough sleep. You can’t remember large chunks on information in one sitting. Stand up and come back to it at a later time.
  • M is match learning and testing conditions. Learn in similar conditions as when you will take the test. One tip is to chew gum when studying a certain subject, and then chew the same flavor of gum later during the test. It will help you remember.
  • E is elaborate. Think deeply about the material and make other associations with it.

Quick, Draw!

Can a neural network learn to recognize doodling? Help teach it by adding your drawings to the world’s largest doodling data set, shared publicly to help with machine learning research.

This is really fun and amazing especially when the AI recognizes your drawing in just a few seconds simply based on what it has previously learned from drawings of the same subject by other people.

It’s really interesting too seeing how we differ from each other in imagining and drawing stuff.
