Re: Fermi Questions C

`Given how the moon normally raises tides by 5ft? I would guess that as more mass is added the more the raise goes by. Not doing any "real" math here but logic tells me it would be 100+ times as Fort Collins is above sea level? Final fermi answer 1.8x10^3`
`I presume that the more moons you add it would increase by 16.5 meters and Fort Collins is 1525 meters above sea level then it would take about 91 moons thus a fermi answer of 1x10^3 if you round up. :)`
How many earth moons would it take to equal the mass of Jupiter?

`Mass of Jupiter E27 and moon is 7E22 so E4`
`Jupiter's mass is closer to 2E27 but same answer E4`

Re: Fermi Questions C

Since no one has posted a question, I guess I'll go ahead:

What percent of all deaths in history have been caused by shark attacks?
i can't feel my arms wtf i think i'm turning into a lamp

voted least likely to sleep 2018, most likely to sleep in class 2017+2018, biggest procrastinator 2018

`~9e10 deaths in all of history. Annual deaths are ~e7 of which perhaps ~e2 (probably less than by a bit) die of shark attacks each year, so e-5 of the population dies of shark attacks - extrapolate to get Fermi Answer: 5`
`The actual proportion of current deaths caused by shark attacks is ~1.3e-6, so multiplying that by a total deceased population of ~101 billion yields ~1.3e5 so Fermi Answer: 5`
How many more people are diagnosed with esophageal cancer each year in the US than are diagnosed with mesothelioma?

How can you get anything more than 2 for a percentage?

I've reworded my question to make it more clear.

A percentage goes up to 100 percent... You can't have 130,000 percent of all deaths be from sharks. E5 is the total deaths/E11 which is -6 or as a percentage -4. Also sources I saw online said the rates of deaths were slightly lower so possibly -5

This is a more coherent version of what I was saying.
