SpaceX is renovating the former Falcon 9 first stage test stand at their McGregor, Texas test site. Recent aerial photos show that workers have installed scaffolding near the stand, and have removed the large tower formerly used to access stages on the stand. Elon Musk confirmed the work is related to converting the stand to test Raptor engines. SpaceX is also continuing work on a new second stage test stand.
Circling Wave Umbrella @exploratorium: kinetic art that produces mesmerizing wave structure in a disk of fabric. Follow the white dot on the bottom of the fabric to see the actual rotation rate of the disk. The stretchy vinyl coated spandex is set to spin at about 60 RPM which sets up a dynamical interplay between the inertia of the fabric and air resistance, producing four waves that travel at about 20 RPM. Thus the waves rotate at about 1/3 the speed of the cloth. Similar rotational waves travel around the arms of galaxies! Created by Ned Kahn, long time artist in residence at the Exploratorium.🌟With special thanks to the Exploratorium! ➡️ Follow the link in my profile for more info and where to find many of the amazing items featured here on @physicsfun

Pisces Kinetic Art Lamp: standing waves of a rotating string are illuminated by strobing light in this new kinetic sculpture by artist and computer engineer Stephen Co. With the help of programmable micro-controllers, strips of addressable RBG LEDs are made to flash in sequences that make the rotating string change colors, merge into spoon shaped surfaces, or split into multiple braids. The string is propelled by small motors and the standing waves can have multiple nodes, which can be altered by touching the string while in motion. With sincere appreciation to Stephen @northerncircuits for sending me one of his latest creations. ➡️ Follow the link in my profile for information on where to order this kinetic art lamp and other amazing items featured here on @physicsfun

Steinmetz Bicylinder: intersect two cylinders at right angles and the remaining confined space is the bicylinder- shown here machined from stainless steel. The bicylinder casts a circular shadow along two orientations, and a square shadow perpendicular to those. In addition the curve created along where the two cylinders meet is an ellipse- as seen with the object spinning along the intersection axis. Fun fact: the area and volume of this object are known to be A=16r^2 and V=16r^3/3.

Hexa-Sphericon: Sphericons are unique solids that roll in such a way that every point on their surface comes in contact with the plane- following the path shown here with white paper. Solids from the sphericon family all have one side and two edges. Each sphericon is based on a regular polygon, with the basic sphericon derived from a square, and here- a more interesting case with more complex rolling motion- from a hexagon. ➡️ Follow the link in my profile for info on where to buy sphericons and other amazing items featured here on @physicsfun

Oscillating Cylinder Steam Engine: a functional “wobbler” type piston steam engine complete with boiler and flywheel. In this design the cylinder and piston both rock back and forth, acting as the valve mechanism to allow the hot steam to enter through a small hole, and then exit on the next stroke out through the tiny exhaust port in the top. Takes about 4 minutes to get going after the lamp is lit. A tiny version of the invention that powered the industrial revolution. ➡️ Follow the link in my profile for info on where to get this and other amazing items featured here on @physicsfun

- Eu vejo ondas.
- com que frequência? - depende do gerador.
Pois bem, um motor pequeno de 5 V foi utilizado como gerador. A frequência com que ele batia na corda era o que gerava o comprimento da onda. Em alguns momento é possível observar a reflexão da onda.
A velocidade da onda em qualquer meio pode ser calcula como: v= l.f .
⚛️The United Kingdom has entered the race to build the world’s first prototype commercial fusion reactor. The British government announced a £200-million (US$248-million) investment on 3 October.
Even though no fusion facility has yet been able to generate more energy than it takes to run, governments around the world are already looking at how they might build a commercial reactor. Both the design and timeline for the UK proposal make it among the most ambitious.
Over the next four years, scientists at the Culham Centre for Fusion Energy near Oxford will produce a detailed design for the Spherical Tokamak for Energy Production (STEP), a plant capable of generating hundreds of megawatts of net electrical energy that would be up and running by the early 2040s. If the decision is made to go ahead and build the facility, the bill would stretch to billions of pounds.
“It’s ambitious and adventurous, but I think the fusion programme has to be,” says Howard Wilson, director of the STEP programme at the UK Atomic Energy Authority (UKAEA), which runs the Culham Centre.
The nuclear fusion of hydrogen atoms into helium — the process that powers the Sun — promises an almost limitless supply of clean energy. But no facility has yet been able to achieve the level of heat and confinement needed for a reaction to generate more energy than it takes to produce. The international ITER experiment being built in southern France aims to do that in 2035. The STEP project’s goal is to go a stage further: creating a plant that can harness electricity from fusion. Only if ITER succeeds will scientists know whether a prototype commercial plant such as STEP is really viable. I hope it becomes a reality! 😃

Vertical Mendocino Motor: each face of solar cell is connected to a coil of copper wire. Spins fast and quite in a sunny window. As the rotor turns each solar cell takes a turn in the brightest light, which provides electric current to one of the coils which becomes a temporary electromagnet that pushes against the permanent magnet configuration in the center- propelling the rotor to rotate. The rotor assembly is nicely symmetric and balances on a sharp point for minimal friction. Invented in the 1960s by Daryl Chapin of Bell Labs and popularized by Larry Springs of Mendocino CA ➡️ Follow the link in my profile for more info and where to buy this and other amazing items featured here on @physicsfun

⚛️ The Earth is constantly being bombarded by cosmic rays — high energy protons and atomic nuclei that speed through space at nearly the speed of light. Where do these energetic particles come from? A new study examines whether pulsars are the source of one particular cosmic-ray conundrum. Plead head to the LINK in our BIO to find out what does it mean. 😊 .

What is the reason for all the mosaic edges? Why not a seamless cylinder? Comment your thoughts.
Precision Tippe-Top: spinning things often have surprising physics! This aluminum version of the famous flip-over top works better than any I’ve seen. Friction with the desk surface provides a torque that acts on the existing angular momentum of the top to flip it over. The top will stay flipped until the spin rate slows down enough to where its center of mass pulls it back to the resting position. ➡️ Follow the link in my profile for for details on where to get a tippe-top like this one and other amazing items featured here on @physicsfun

Self-Propelled Homopolar Motor on Aluminum Foil Racetrack: A favorite DIY physics toy where disk shaped neodymium magnets supply the static magnetic field for this motor and become the wheels of a very simple vehicle with an AAA battery as the energy source. As soon as both ends make contact with the conducting aluminium foil an electric current will flow, which in turn induces a magnetic field underneath the battery assembly. This induced field will then interact with the neodymium magnets on each end causing them to spin- a wonderful example of a motor with minimal components. The racetrack is a cardboard circle from a pizza box covered in kitchen foil. ➡️ Follow the link in my profile for info about how to make this and find other amazing items featured here on @physicsfun

گهواره نیوتون(Newton's cradle)
دستگاهی هستش که از رشتهای گویچهی تابخورنده درست شده و پایستگی تکانه و پایستگی انرژی رو نشون میده.
در سال ۱۶۸۰ میلادی توسط نیوتون ساخته شده، و هنگامی که یکی از گویها در یک سر گهواره رها بشه، نیروی پدیدآمده از خطِ تماس گویچهها میگذره و گویِ سر دیگر را از جا بلند میکنه و این روند ادامه داره....
گهوارهٔ نیوتون رو آونگ نیوتون و گویهای نیوتون هم صدا میزنن.😉

⚛️ Hidden 1,000 metres under Mount Ikeno in Japan is a place that looks like a supervillain's dream!
Super-Kamiokande or "Super-K" is a Neutrino detector that detects Neutrinos. Neutrinos are the subatomic particles that travel through space and pass through solid matter as though it were air or so to say no obstacles in their path. 😯 Studying these particles is helpful in detecting dying stars and learn more about the Universe.
