I meant to write ---
For all real numbers x, sin2 (3x) + cos2 (3x) = ???
Answer's still the same.

You don't have to use pen and paper. Mental math is fine, the answer is 5.

Calculate what would have a larger force on you when you were born: a nurse in the delivery room or a star (excluding the Sun) in the sky.

In the sky, like in the atmosphere? The first force I went to calculate has a few parameters missing: size of star/nurse, distance of star/nurse (nurse is estimatable).

OK, the star is Proxima Centauri and the nurse weighs 70kg.

Actually, never mind. I can give you an answer in Newtonian mechanics using Gravity as a Force. But then Einstein showed up and ruined everything, making gravity not a force and I stopped studying physics after first year. You would have to ask a real physicist for an actual answer. Sorry, saxi, I hate to let you down.

The closest star is Alpha Centauri, you can easily find info about it on wikipedia. As for the nurse, just estimate roughly the weight and distance.

Make the nurse 150 kg. And make her a wet-nurse. And multi-orgasmic. And a Valkyrie.
Make the star Betelgeuse. No, make it Beetlejuice. Ah, hell. Just make it Micheal Keaton.
Now put them in a bathtub. With Archbishop Makarios.

The average human's force of pushing/pulling is on the order of 100 Newtons (this is an SI unit). Proxima Cen is about one-tenth the mass of our Sun, and a distance of 1.3 parsecs. Assume the baby has a mass of 3 kg. In SI units, the gravitational force is 3 x 10^(-14) Newtons. Or, in scientific parlance, really f***ing small. The nurse is about 100 trillion times stronger than the star.

I think saxi is asking if the gravitational force exerted by the nurse or that exerted by the star is larger. (hopefully it's pretty clear that a human actually pulling something exerts more force on that object than proxima centauri does)
If my calculation is right the nurse actually exerts more gravitational force by about 6 orders of magnitude (assuming she's standing within 1-2 meters of the baby)

Well, saxi's pretty old. You can never be sure with him.

Is that necessarily obvious to someone who doesn't know the intrinsic strength of the gravitational force? I don't see why.

Yes, that is correct.

Would it be the same if it were BBS instead of a nurse (assume BBS also weighs 70kgs)?
How did you arrive at a factor of six, Haggis/Max?

Hmm, well if proxima centauri exerted that much force then the force exerted by our sun would have to absolutely dwarf the pulling power of a human, so then I guess you'd expect to see objects wildly flying about as the earth gets closer or farther away to the sun.
Though yeah, maybe it's not obvious if you've never thought about it / have no idea how gravity works.
saxitoxin wrote:How did you arrive at a factor of six, Haggis/Max?
Gravitational force between object 1 and 2 situated at distance d is roughly g*mass1*mass2 / d^2
So force exerted by star divided by force exerted by nurse is: mass_star * dist_nurse^2 / (mass_nurse * dist_star^2 ). mass of proxima centauri is 0.123 solar masses = ~ 2.5 * 10^29 kg distance to proxima centauri is 4.24 light years = 4 * 10^16 meters mass of nurse is 70kg assume distance to nurse is 1m Plug those in and you get that force_star / force_nurse = ~ 2 * 10^-6. So the force exerted by the nurse is about a million times stronger than that exerted by the star.

As an economist BBS is not allowed within a 1 mile radius of any maternity wards. Modifying the distance to BBS from 1 meter to 2000 meters actually means proxima centauri would have a sliightly stronger gravitational pull on the baby than BBS would.

What if BBS was right at the legal limit of 1600 metres?

Not possible, according to the uncertainty principle.
