`The Lense-Thirring effect, a prediction of general relativity, implies that massive rotating objects like Earth can slightly "drag" spacetime, which could affect the pendulum's oscillation. This effect, though theoretically significant, is currently too small to measure with a Foucault pendulum.`

Можно ли заменить datetime? Как Pendulum делает работу с датой и временем удовольствием
Работа с датой и временем в программировании — это одна из тех «темных» областей, на которой каждый разработчик набивает свои шишки. На первый взгляд все просто: from datetime import datetime, datetime.now(). Что может пойти не так? А потом в проекте появляются часовые пояса, и начинается тихий ужас. Вы внезапно обнаруживаете, что стандартная библиотека Python оперирует двумя видами объектов: «наивными» (naive), которые ничего не знают о своем часовом поясе, и «осведомленными» (aware), у которых эта информация есть. И datetime.now() по умолчанию создает именно «наивный» объект, который в лучшем случае бесполезен, а в худшем — источник трудноуловимых багов, когда ваш код запускается на сервере в другом конце света.

Made to order small #leather #pouch for a #pendulum . This is really #small and made by the measurements my customer provided about her #gear . I even tested that it does not provide much use for #coins either :D - but certainly may be #alter -ed to fit some.

A nice clear explanation of something which I'm sure a lot of people find a bit odd at first.
Now, while you've still got your Superman T-shirt on, you may also like to impress your friends with this one: https://www.youtube.com/watch?v=efvT2iUSjaA

A few days back, I posted some #AnimatedGifs of the exact solution for a large-amplitude undamped, unforced #Pendulum. I then thought to complete the study to include the case when it has been fed enough #energy to allow it just to undergo #FullRotations, rather than just #oscillations. Well, it turns out that it is “a bit more complicated than I first expected” but I finally managed it.

Pendulum are officially stepping back into the spotlight with a brand-new album on the way. This week, the legendary electronic-rock group revealed that their fourth studio album, INERTIA, will be released on August 22nd—marking their first full-length project in 15 years.

The above is only strictly true for “small” amplitudes. If the #pendulum is subject to large amplitudes, it is no longer governed by the simple linear differential equations alluded to above. Given that the rod remains rigid and no energy is dissipated, the pendulum #equations may still be solved exactly, though they are now #nonlinear.

A cycloidal pendulum - one suspended from the cusp of an inverted cycloid - is isochronous, meaning its period is constant regardless of the amplitude of the swing. Please find the proof using energy methods: Lagrange's equations (in the images attached to the reply).
Background:
The standard pendulum period of \(2\pi\sqrt{L/g}\) or frequency \(\sqrt{g/L}\) holds only for small oscillations. The frequency becomes smaller as the amplitude grows. If you want to build a pendulum whose frequency is independent of the amplitude, you should hang it from the cusp of a cycloid of a certain size, as shown in the gif. As the string wraps partially around the cycloid, the effect decreases the length of the string in the air, increasing the frequency back up to a constant value.In more detail:
A cycloid is the path taken by a point on the rim of a rolling wheel. The upside-down cycloid in the gif can be parameterized by \((x, y)=R(\theta-\sin\theta, -1+\cos\theta)\), where \(\theta=0\) corresponds to the cusp. Consider a pendulum of length \(L=4R\) hanging from the cusp, and let \(\alpha\) be the angle the string makes with the vertical, as shown (in the proof).#Pendulum #Cycloid #Period #Frequency #SHM #TimePeriod #CycloidalPendulum #Lagrange #Cusp #Energy #KineticEnergy #PotentialEnergy #Lagrangian #Length #Math #Maths #Physics #Mechanics #ClassicalMechanics #Amplitude #CircularFrequency #Motion #Vibration #HarmonicMotion #Parameter #ParemeterizedEquation #GoverningEquations #Equation #Equations #DifferentialEquations #Calculus
