The goal is to combine the 6 numbers to a total of 100. You can use the mathematical operations + - * / ^ and the parenthesis ( ). Numbers can be combined, but you have to use all 6 of them and are not allowed to change the order. See https://hectoc.seism0saurus.de for an example. Please use CW "solution".

People "prioritized efficacy over quality-of-life" more for some #ethics prompts than other "normatively equivalent" prompts.
Better performance on #math and #logic reflection tests predicted less vulnerability to this #bias.
How much total drag does my truck create while moving down the highway?
Measure it indirectly!
Run cellphone GPS logger at 1-second interval. Get truck up to speed on flat section of highway, put transmission in neutral, foot off the gas. Let the truck slow down 30 - 45 seconds to get a decent number of data points. Make another data run on same section, but opposite direction to average out effects of wind and any slope.
Import GPS log into spreadsheet.
A linear fit gives you a straight line slope...good enough to determine deceleration...then apply that to F = m * a (you need to know truck's weight) Now you know total drag force at one speed.
Total drag is air resistance (varies with square of speed) plus rolling friction (assume it's constant). OK, do a quadratic/polynomial fit. Now you know rolling friction. Subtract from total drag, and you can determine area-drag (Cd * frontal area) of your truck.

What's a better predictor of med. students' accuracy in #diagnosis?
- #Motivation to become a researcher
- #Math ability
Among 128 students of #medicine, #numeracy was *much* more predictive of scores on medical cases involving #probability.
So the next time you Google something, remember Andrey Markov who, quite literally, helped the web find its way.

I sometimes wonder if I lived in the age of Greek geometry and visual proofs, I'd be a mathematician. I feel like at some point the algebraicians won and made things very difficult for visual thinkers.
Do you ever get to the point where you can fluently read pages of terse mathematical symbols like https://www.gregegan.net/SCIENCE/Rings/Rings.html, or are you just meant to skim them and are supposed to spend hours painstakingly substituting values and solving them manually to ever get anything close to an intuitive understanding? #maths #math #mathematics #geometry

You see a math formula you don’t immediately understand.
Your instinct? Stop reading.
Don’t.
That’s exactly what I told myself when I started reading Probabilistic Machine Learning – An Introduction by Kevin P. Murphy.
And it was absolutely worth it.
In my last article on Towards Data Science, I took a probabilistic view of supervised, unsupervised & reinforcement learning 👉 https://towardsdatascience.com/beyond-glorified-curve-fitting-exploring-the-probabilistic-foundations-of-machine-learning/
