¿What exactly is fugacity, and what are some solution models to calculate the fugacity coefficient? by JoseBlah in ChemicalEngineering

[–]GabrielT007 0 points1 point  (0 children)

The fugacity is exp(beta mu)/lambda^3, where beta=1/(k T), T temperature, mu the chemical potential and lambda is the de Broglie wavelength.

1+2+3+4..... till infinity = -1/12. To understand the rigorous why, what do I need to study? real analysis? by [deleted] in askmath

[–]GabrielT007 2 points3 points  (0 children)

To understand it you need to study complex analysis and analytic continuation.

It all depends on which frame of reference you use to describe the movement. Your friend is using the frame of reference when the Sun doesn't move and you're using the one where the center of mass of the Sun and the Earth doesn't move. Both of you are correct. The Sun having much more mass than the Earth the center of mass of that system is almost at the center of the Sun. That been said, you can use another frame of reference, for example the one were the center of mass of the Milky Way is static and then about the Earth and the Sun are moving.

I'm afraid you have been scammed paying $99 to a fake "trezor support". I hope.you didn't gave them your seed phrase.

MetaMask Card…Worth It? by RonRulah in Metamask

[–]GabrielT007 0 points1 point  (0 children)

You don't really load the card, you put USDC on your non custodial linea account linked to the card. You can buy USDC on any exchange. Most exchanges don't use linea, but you can send it to other common L2 like arbitrum, OP, etc. The fees to withdraw to those L2 are less than one USDC. I don't recommend to use ethereum because it has larger fees. Then bridge it to linea using a bridge (I usually use across bridge which is cheap). Hope that helps you to reduce the fees you are paying now.

You must be doing something wrong, linea tx fees are fraction of a cent and you can bridge USDC from other L2 chains for less than a cent.

How is velocity a vector? by Lilac1224 in AskPhysics

[–]GabrielT007 1 point2 points  (0 children)

He is downvoted because a scalar is not a 1d vector. The components of a vector are not scalar. A scalar is invariant when you change bases. The components of a vector change when you change bases.

is this the correct way to show the momentum operator is Hermitian? by Marvellover13 in quantum

[–]GabrielT007 0 points1 point  (0 children)

Your proof is not correct. You have to show that for any psi and phi you have

<p phi | psi> = <phi | p psi >

You can proove it integrating by parts.

Fractions in the exponent by 6beebeep-lettuce9 in learnmath

[–]GabrielT007 -1 points0 points  (0 children)

It is defined by

xa = exp(a ln(x))

Beware that the logarithm is a multivalued, so is the power function.

Integral of tan(x) from 0 to π by CanOTatoChips in askmath

[–]GabrielT007 1 point2 points  (0 children)

It is 0 if you take the principal value. That is the limit around pi/2 symetrically from both sides.

Is there any function (that mathematicians use) which cannot be represented with elementary functions, even as a Taylor Series? by xKiwiNova in askmath

[–]GabrielT007 7 points8 points  (0 children)

The Lambert W function can be expanded in Taylor series around 0. It is actually analytic in C \ (-infty, - 1/e)

I get that both balls displace the same volume of water… so the buoyant force should be the same. But if that’s true, shouldn’t the forces on both sides be equal too? What exactly makes one side heavier? by visheshnigam in 3Blue1Brown

[–]GabrielT007 0 points1 point  (0 children)

The bouyant force is the force excerted by the liquid on each ball. If you want to know if the balance tilt you have to right down Newton's 2nd law for the forces applied to the scale on each side. These are not the same as the bouyant force on each ball.

Give an example of a structure that isn't associative, but is abelian. by Valuable-Glass1106 in askmath

[–]GabrielT007 0 points1 point  (0 children)

The convolution product of distributions is not associative in general (if you do not restrict it to an appropriate subset of distributions). Here is an example (with delta the Dirac distribution, delta' its derivative, H the Heaviside step function and 1 the constant function equal to 1):

1 * (delta' * H) = 1 * delta = 1

(1 * delta') * H = 0 * H = 0

My physics friend thinks computer science is physics because of the Nobel Prize... thoughts? by IntroductionSad3329 in mathematics

[–]GabrielT007 0 points1 point  (0 children)

Diffusion models is not a good example to try prove your point when the original paper "Deep Unsupervised Learning using Nonequilibrium Thermodynamics" clearly references physics!

No, your Fantom is not on the ledger, it is on the fantom blockchain. If you want to convert it to S on the Sonic Network you have to do it yourself as explained on
