RE: Tuesday Scientific Owl Curation (SOC) #6
Thanks for mentioning me, and more importantly thanks for questioning, which is quite important in a time when everyone accuses everyone else of publishing "fake news". As with any knowledge,

RE: The Dysteleological Argument: Some Things About The Human Body Make No Sense Whatsoever (Part I)
The notion that the body is a "finely tuned machine" hasn't exactly left us from classical antiquity. The vertebral column is perhaps another quirk of recently bipedal humans. It works better

I like your style. This is a humorous poem and the use of Scots makes it seem unique.

For me, it's younger children (Year 1 through Year 6), then first year university students, then older high school. The middle years students tend to be hit or miss, until they realize that they need you

RE: Mathematics 2nd grade class / Multiplication strategies
This is a very good post. I admire those who can explain essential mathematics to the very young. It's a talent I admittedly have never developed. I must admit that I envy those who can do it.

RE: Track the Chinese Tiangong-1 Satellite as it Falls to Earth
It was originally supposed to be decomissioned in 2013, but stayed until 2018. Anyhow the Tiangong-2 was launched in 2016.

RE: The math of connecting galaxies in an efficient way
Thanks for dropping by my blog! And thanks for actually taking the time to ask questions, even if it was a hoax post. This is a very interesting post. It's been a while since I heard about Prim's Algorithm.

RE: Brainsteem Mathematics Challenges: Factoring Seconds
I thought that at first but I think it only works if all the items are indistinguishable, which they're not. You have to consider the fact that grouping something (x x y) (y y x) is slightly different

Can't we just use Stars and Bars here? There are 86400 seconds in a day and 86400 = 27 • 33 • 52. According the S&B Theorem, there are (n+k-1)C(k-1) ways to divide up n items into 3 bins (with the

RE: Brainsteem Mathematics Challenges: Pairwise Sums
For the case with three numbers, assume you have values x, y, and z arranged in ascending order. Then it follows that x + y is the smallest sum and y + z is the largest sum. Adding all pairwise sums gives

For the first one, you can solve them algebraically. In the second one, HF = EG because they're diagonals of the same rectangle.
