I always liked math puzzles and stuff. Thought maybe some of you would like this nutty little dude's channel.

There are girls on the channel too -

If you aren't a math-geek you won't likely enjoy these....

Several decades ago, I got A's all the way through third-year calculus, but really can't understand half what she talks about....!

Powers of Ten

it helps me think about 8.4x10-123rd

that's a big big big number and the illustration is mind boggling . . .

I got through Calc 3, but I didn't really learn it. Having access to the Engineer who designed the Trident was helpful. He is passed on, so I have to use the internet now.

As far as understanding numbers, there is a lot I will never understand.

LOL - in Pharmacy School, they seemed to think we were all going to be pharmacokinetics program developers... :D

Med school was way easier academically - but the mind-game stuff and one-upsmanship was insane.

I can see that. For example, Xyzal is half the strength of the parent pro-drug Zyrtec. Xyzal loses half of its strength on the first pass through the liver. Zyrtec is activated to Xyzal on its first pass. No loss of medicine at all. On the second pass, Zyrtec is down to about 5 mg of active Xyzal. On the second pass, the Xyzal is down to about 1.25 mg of Xyzal. AND THE ADVERTISEMENTS TELL US THAT XYZAL IS BETTER. They know that the average person is not going to pay any attention at all to kinetics.

When Allegra came out, it was the active metabolite of Seldane. Seldane was a prescription antihistamine which had problems where it competed with -mycin antibiotics for liver chemicals to be broken down. Allegra was already the broken down to active chemical. As soon as Allegra went through the liver, it lost half or more of its strength. Seldane lost no potency because it was activate to Allegra. Both were 60 mg in the beginning. When the first sales rep for Allegra came through, I pointed this out. She got angry and told me that I had no business questioning the research scientists. About 6 months later, the 180mg Allegra came out because the 2 tablets of 60 mg each per day were not strong enough. I may not be able to understand all mathematics, but I am not completely an idiot.
