What would you say if you met a woman as beautiful as Marilyn Monroe and as intelligent as Albert Einstein?

Are there or financing/doing research in either theoretical quantum information, data science or machine learning who need a theoretical physicist who likes to play around with data and has a solid background in math?

Hey, I'm Charlie. I'm part of the doctoral training centre at University College London for delivering quantum technologies. I'm just finishing up a master's project and will be a PhD candidate starting October this year.

For my master's and PhD I'm investigating efficient and practical ways of encoding fermionic systems (electrons, essentially) onto quantum devices for simulation.

Interested in any quantum technology related content.

#introduction I'm James, a NatSci student, #programmer and dinghy instructor. Looking to see cool new things and get to know interesting people/bots! #robotics #scicomms #programming #tennis #bots😊

Heute mal die Filterlisten in pi.hole überarbeitet. Nachdem ich auch eine für Fakenews aboniert hab, löst Bild.de nicht mehr auf. 😂

Das fühlt sich hier an, als hätten sich ein paar Leute bei Twitters Party durch den Personaleingang rausgeschlichen und feiern im Hinterhof ne bessere Party. Werbefrei. Mit allen Songs in der richtigen Reihenfolge. Ohne Brüllaffen.

Fun with spoons

How do you find the center of mass for any given geometry even if you have no idea on how to solve this analytically?

a) You can try some numerics.
b) You build a 3D replica and try to balance it on your fingertip. Works pretty well for spoons. Take a spoon, try to balance it -> yep, you found the COM.

Some more physics. You balance that spoon and add some small perturbations. Does the spoon hold? Congratulations, you just found a stable minimum.

How to describe this mathematically? -> Taylor series.
Dirty way - do a Taylor series expansion of the equation of motion around your extremum. Try to solve the differential equation with an ansatz combining two exponentials, one with a negative sign in the exponent, one with a positive one and both with different coefficients. The coefficients depend on the initial conditions but the exponents come from the solution of the differential equation.
If the exponent is imaginary you get a linear combination of cosine and sine functions. Congrats! For small perturbations your system will oscillate around the minimum but not leave it. You found a stable (maybe local) minimum.
Your exponent is real. Damn you found an unstable maximum. Try again.

Interessant zu sehen, dass all die alten Piraten der ersten Stunde jetzt auf chaos.social zu finden sind. Gefällt mir.

@tootapp This is no coincidence. Take a closer look at the accounts that write you: most of them will come from chaos.social. Two communities are gathering there: the German hacker community of the Chaos Computer Club (who run the server) and the German podcasting community around the so called "Sendegate". Both groups, which appreciate open source very much, program themselves and like to give feedback to open software. You did everything right.

So many interesting people on @chaos.social . This is really amazing <3
