No. The yolk part of an egg has a smaller variance than the white part. The commercial eggs are bigger (have bigger whites or two yolks) because they hens hormonally stimulated and fed more protein. Generally big eggs are not healthy either for those who eat them or the hens who have to lay them.

what is the standard when it comes to units

\(\frac{G\times 1 \mbox{ weight unit}}{c^2}=\frac{G}{c^2}= \mbox{ meter}\)

that is output unit is meter as I am looking for in this case, but one could claim

\(\frac{G}{c^2}\) alone not give meter output, but \(m\cdot kg^{-1}\) as output, since G is of form \(m^3\cdot kg^{-1}\cdot s^{-2}\)

In other words can I write just \(\frac{G}{c^2}\) and claim output is in meter, because I actually have \(\frac{G\times 1 \mbox{ kg}}{c^2}\), or should I then write out as \(\frac{G\times 1 \mbox{ kg}}{c^2}\) every time, as then evident output is meter. When multiplying with 1 (unit of something) it naturally only changes the units, not the output number.

Writing another groundbreaking scientific paper or book? The standard is using square brackets (see dimensional analysis).

yes i know that ( dimensional analysis ) , but seems no one has walked this particular theritory...

"Writing another groundbreaking paper"

yes writing a paper, it is not groundbreaking, it is breaking G, not the ground. To break the ground I use my new Lamborghini, except close to my hedge where I have to do fine cutting off long grass by hand (to not damage the Hedge with my over sized Lamborghini) , where the damn snake was hiding. Some hedges are more risky than others!

I've seen different conventions, but I think the standard is:

\([\frac{G}{c^2}] \cdot{kg}= \mbox{meter}\) - if you want to talk about units.

\([\frac{G}{c^2}] \cdot{M}= \mbox{L}\) - if you want to talk about dimensions (L and M are length and mass).

\([\frac{G}{c^2}] \cdot{kg}= \mbox{meter}\) - if you want to talk about units.

\([\frac{G}{c^2}] \cdot{M}= \mbox{L}\) - if you want to talk about dimensions (L and M are length and mass).

You're welcome.

BTW, maybe you should follow Paul's example and take fancy of long grass?

To me, both you and Paul are completely alien species.

i have met both of them, and they're not completely alien. Originals? Yes!

Looks like I need the Lambert W function to find some type of maximum I am looking for. In mathematica this is ProductLog function, dose it also exist built into excel under some name?

also since I am new to the Lambert W function, is there any interesting stuff I should know about it? Implementation wise or otherwise?

In maple, it's LambertW(x)

I first came across it in maple when for some insane reason they decided to make it just "W(x)" in the then-latest version, and since everyone was using (U,V,W) for velocity, it didn't exactly go down well. And they didn't even tell you that W(x) had suddenly become the LambertW function. I had codes that were supposed to be finding W(x) and they were giving gibberish because W(x) had already been defined by the system

I' m sure mathematica can plot it and evaluate it.

yes Mathematica can do it, still struggling with the intuition behind Lambert W...should be a simpler method (to find my Omega point) ...

Maybe Maple made it well-known to computer guys, but solid state physicists have been using W for solving the particular type of differential equations since Lambert came up with his method.

I met one of them; what's the other one like?
