I know it is highly corrosive?

Comment on As a Man, I Also Care About #ShirtStorm and STEM Sexism by Judith https://eportfolios.macaulay.cuny.edu/sciencefordessert/2014/11/19/shirtstorm_stemsexism/#comment-51002 Sun, 22 Aug 2021 00:32:48 +0000 http://eportfolios.macaulay.cuny.edu/sciencefordessert/?p=443#comment-51002 “There is little risk for men to address sexism in any field, which is just one more reason to add our voices to the conversation. We need to show our colleagues, male and female, that we stand against this blatant misogyny and that this kind of abuse should not be tolerated.”
In Switzerland, which is where I’m from, women’s suffrage wasn’t granted until 1971, due to the many elements of direct democracy in our country. It meant that the majority of adult men in Switzerland had to vote “yes” when they were asked if they wanted to grant women the right to vote. I firmly believe that as soon as the majority of men stands up against misogyny and sexism, things are gonna change for the better of everyone. Thank you for your contribution – it makes reading all those negative comments on social media a lot more bearable.

Comment on Will The Earth Collide With The Sun? (No) by danielfeldman https://eportfolios.macaulay.cuny.edu/sciencefordessert/2012/08/06/will-the-earth-collide-with-the-sun-no/#comment-16953 Thu, 01 Aug 2013 16:32:34 +0000 http://eportfolios.macaulay.cuny.edu/sciencefordessert/?p=276#comment-16953 In reply to Sreehari G Varma.

I’m sorry that my example was a little confusing. It’s the Sun’s gravity that actually keeps Earth going around in its orbit. Perhaps my first bucket example is better:

When you swing a bucket around in a circle, your act of pulling on it is what makes the bucket swing around. Your pulling gives the bucket a fast enough speed and enough angular momentum to move in a circle and not fall down. The Earth is like the bucket and the Sun is like you–its gravity is what does the pulling, and makes the Earth swing around in its orbit. In order to fall into the Sun, Earth would have to slow down, but that doesn’t happen because there’s nothing to make it slow down. Gravity is the only major driver of Earth’s motion (and it is what keeps Earth going around so fast), so unless something really massive comes along, Earth will continue to stay in this orbit.

But i have a confusion- like the example you gave of the spiral wishing well coin funnels, why don’t the earth collide to the sun like the coin to the hole??? Isn’t it true that the sun exerts a gravitational pull on earth??? So obviously the angular momentum of the earth will experience an external interference leading it to change its direction towards the sun. Therefore it must collide into the sun one day… Please reply and clear my dought.
hopefully waiting for the reply.

That’s a great question—I’m not 100% sure, but I consulted the fellow grad students in my office and I’ll give you our decided answer. So I talked about how H- creates opacity in the Sun’s atmosphere because it absorbs light to ionize, but it also emits light during it’s formation (the capture of the second electron creates an emission at one specific energy). If there’s a steady state—just as many created as destroyed—then getting rid of the H- wouldn’t change the outward brightness of the Sun, so the Earth’s temperature would not be affected. If however, there isn’t a steady state, then whatever energy is getting stored or generated in the creation or destruction of H- would go away if removed, and then there would be a temperature change here at Earth. To our knowledge, there is a steady state, so we agreed that we think there’s be no brightness (and therefore temperature) change here. However, what would happen for sure is that if you pointed a telescope at the Sun, if H- was not present than you would be able to see to greater depth inside the Sun (more transparency).

What would happen if H- was not present in the sun? Would we’d fry?

Awesome! I think H- is also important in other chemical reactions with heavier elements too. :)
