Physics 11: Simple Machine and Mechanical Advantage

Hi Everyone,

We saw two example of lever today (pop can tab, meter stick lever) in class and learned about how they can help us "magnify" forces with mechanical advantage. Hopefully you'll notice the tools around us that use simple machines as well!

Science 10H: Blackbody Radiation (Mar 12)

Hi Everyone,

We investigated blackbody radiation from us and the stars in two aspects today: color and power. With higher temperature, blackbody radiation moves from infrared to visible light, so hotter stars are actually bluer, while colder stars are redder. We also found out about blackbody radiation from us. We emit in infrared and makes a few hundred watts of blackbody radiation.

Science 9H: Meiosis and Sexual Reproduction (Mar 9)

Hi Everyone,

It's crazy how there could be 2^46 combinations for human offsprings! It is almost impossible for parents to give birth to two offsprings of the same genes, unless they are identical twins.

Physics 11: Mechanical Advantage and Simple Machine (Mar 9)

Hi Everyone,

We've learned about how a lever work today. Measuring these quantities tell us how simple machines help us, just like the pop can tab!
