Avogadro's Hypothesis

The hypothesis (now referred to as Law or Principle) states that equal volumes of all gases at the same temperature and pressure contain the same number of molecules.

A hypothesis is a proposed explanation, based on current truths, that still awaits proof.  Avogadro was bridging the ideas between John Dalton and Joseph Louis Gay-Lussac, and thus formulated his hypothesis.

The Mole

 Basically, the mole is a unit.  The mole is an Avogadro's number of anything, ie 6.022x1023 of anything = 1 mole.  The original idea was to be able to measure the amount of molecules in a certain volume of gas, but its usefulness quickly extended much further.

    Your succinct summation of Avogadro's hypothesis, Avogadro's number and the Mole concept is something I found to be easy to understand and memorable. It would be perfect content for anyone brand new to the topic who does have time review a lengthy document.

Week 4 Physics

 How has e=mc2 affected you? So, full disclosure, I wholeheartedly revere Einstein as a mammoth of a genius, and believe he ultimately had it more right than any other scientific thinker.  Including the Bohr-Einstein debate.  He's the Godfather of Quantum, and helped solidify the current theory by rightfully pushing up against it.  And it's still incomplete.  And guaranteed to be replaced.  Einstein lost the debate in terms of majority consensus, but in multiple alternate universes the theory took his perspective to greater benefit.  How would you compare the four “forces”? I've seen the forces listed from strongest to weakest in two ways.  The first like it was presented in class - strong nuclear force/electromagnetic force/weak nuclear force/gravity.  The second way from strongest to weakest - strong nuclear force/weak nuclear force/electromagnetism/gravity.  I'm sticking with the former, since its easier to remember the electroweak ...

Week X: Chemistry

Investigate the chemicals... I've got a shmorgishborg of products underneath the sink, a spectrum of chemicals ranging from the benign to the outright toxic.  I'd say I prefer to use more natural products, but when it comes down to it, I kind of just use what's around and try not to overthink it.  I think it's OK to be mindful of the cleaners you're using and to "use with caution" when necessary.  For the most part, I wear vinyl gloves or something similar when I do the deep cleaning, and try to remember to crack a window for ventilation.  On the safer side of things I have vinegar and castile soap, and on the more toxic side things like bleach, Kaboom (have no idea what this is but most likely some sort of bleach compound), stainless steel cleaner (contains petroleum distillates), and a product called CLR (propylene glycol ethers and other solvents). Examples of "safer" alternatives I said I would post some of the recipes I use for DIY hous...

Newton's Three Laws and Me This is a response reposted from reddit from the query "How do Newton's Laws and Einstein's Theories Contradict?", I just really like how this was stated: level 1 Weed_O_Whirler Aerospace | Quantum Field Theory 10 points · 4 years ago Newton's Laws are known as the "slow speed" approximation of physical laws (they are also the "large scale" approximation- we talk about this when we are discussing how they contradict Quantum Mechanics). What is important to remember, it isn't that Newton's Laws are "wrong" and Einstein's Laws are "right." Both sets of laws are mathematical models of what actually happens, and Einstein's Laws cover a wider variety of cases than Newton's Laws, but they are still a model, which does not perfectly predict all situations. Now, as for the differences, Newton's Laws explain what happens when large things move slowly (lar...
