Launch Pad Astronomy: Neutron Stars, Pulsars and Magnetars at https://www.youtube.com/watch?v=tWsWcWAcK2U For the Internet Foundation, I had to add KiloTesla and MegaTesla to “commonly used units”. Yours is an early example of GigaTeslas, so there will be more. Gravitational energy density, magnetic energy density and many other kinds of energy density can all be interconverted now.

Adiabatic Flame Temperature at https://www.youtube.com/watch?v=AwgQvi1Y24o I would pre-heat the oxygen and fuel molecules electromagnetically. Then record the 3D volumetric temperature distribution, tracking flow of reactants. To start. And find the temperature dependent heat capacities data or models. To start. Calibrate and optimized the linked models. Track spectroscopic IR, VIS, thermal, UV, whatever is available. Share

ElectoBoom: Making a Water Railgun at https://www.youtube.com/watch?v=Qy81O7LrB84 1 cubic centimeter of water is 1 gram = 1E-3 Kg. Add 1 Watt Second = 1 Joule of energy. (1/2) * m * v^2 = Joules Velocity_meterspersecond^2 = 2*Joules/Kilograms Velocity_MetersPerSecond = sqrt(2*Joules/Kilograms) sqrt(2*(1 Joule)/1E-3 kilogram) = sqrt(2000 Joules/kg) = 44.7213595 (m/s) = 100.0388320956 Miles per Hour Note:

Julian Stirling @stirling_julian I’m delighted to still be publishing papers almost 2 years after leaving academia to become freelance. This article is more of a “rant with references”, I try to tackle the problem of perverse incentives that prevent open science from flourishing. https://royalsocietypublishing.org/doi/10.1098/rsta.2023.0215 Replying to @stirling_julian There are fundamental experiments that can examine fundamental

Nancy Grace Roman Space Telescope, If I were going to look at the Galactic Plane now, I would look for evidence of civilizations of two types. The human species is going to produce intelligent machines. Their size and shapes and abilities are open. But in terms of human knowledge one very likely outcome is that human

Humans can colonize Milky Way Galaxy with intelligent devices, and search for gravity signals. — Galactic civilizations using intelligent devices can live billions of years. So the most likely “species” for human devices to meet would be intelligent devices. Nancy Grace Roman Space Telescope might look for intelligent messages in the galactic plane. And space

Put the data from your devices on the Internet and share it live 24/7 with everyone in the world, so it is “all humans” not just “us”, then I will start to believe your words. Archive the noise so it can be studied. You can get to where your systems are sensitive gravimeters, and

Every frame of every video posted on the Internet, generated by diffusion and algorithm, could be dated, tagged and traced. If all copies are different, then it is hard to know which part is the tag. There are people who know how to do that fairly and usefully. Each person sees a unique video, the

Physical Review Letters @PhysRevLett An exact full set of matrix product states of highly degenerate tricritical Lifshitz points in the quantum spin model with anisotropic interactions has been discovered https://go.aps.org/3Q3Pxna https://pic.twitter.com/w22Em2B3EZ Replying to @PhysRevLett It only looks simple because you use simple potentials with no real world inputs. In the real world, every tiny cubic
