Price's Law is a hypothesis that in an organization, or across an industry, roughly half the productive output is being generated by a number of people equal to the square root of those participati...
I feel like science fiction doesn't have many sports, other than the occasional laser battle or fantasy sword duel. I'd like to start a discussion series about sports in a low-gravity/no-gravity e...
The polar vortex nearly dies every year around springtime in the hemisphere you are concerned with. This failure is what brings those spring frosts in February, March. It's not really possible to ...
The Earth-Moon Lagrange points have names: L1, L2, and L3 are Libration Points, the L4 and L5 points are the Kordylewski Clouds. The Jupiter-Sun L4 is named the Greeks, and the Jupiter-Sun L5 is n...
I recently learned that it's believed that the solar system once had one more gas giant, which was ejected by Jupiter some time in the past. https://thesolarsystem.fandom.com/wiki/Fifth_Giant Doe...
I was investigating a few ideas on recreational solar sailing, and came up with some interesting things - The primary equation in solar sailing is $ F = {{2 R S A} \over {c}} \sin^2{\theta} $ Whe...
Low gravity golf was invented by Alan Shepard in 1971 when he hit two golf balls 40 yards on the moon. Surprisingly, this version of the sport with little atmosphere and much lower gravity, is the...
Looks like it may just be mechanical. According to this article, if true, you can rehydrate white glue with water and heat. https://simpleglue.com/how-to-revive-elmers-glue/
I was recently introduced to the South Atlantic Anomaly. As I understand, for satellites and space craft, this is a natural feature that can wreck space craft by taking even computers designed fo...
Theory If I am understanding this history of this correctly, in the 1920s the mathematical process of converting measurements with a certain amount of measurement error into numbers, then doing yo...
How would competitive wrestling change in a microgravity environment?
Any volume is large enough for rain or fog. Humidity buildup (rain) is a concern in spacecraft design, and was one of the reasons (too much rain) that caused one proposed Martian settlement to fail...
Under "Making a Good First Impression", a few mechanical notes from someone just making the transition from WB.SE to Codidact - Question titles should probably be at the top of the page, inste...
I'd recommend a Kalman filter to increase measurement accuracy to the overlap of multiple system errors so that you get the best result. For inputs, may I recommend - a calculation of doppler s...
You have mass flow rate and velocity, but the area this is spread over will say a lot - $$\dot{m} v = F = 1 {{kg} \over {s}} \cdot 1,000 {{km} \over {s}} \cdot 1,000 {{m}\over{km}}= 1 \times 10^{6...
According to this site, the kinetic energy of the two alpha particles emitted is 4.273 MeV. As you said, these aren't neutral atoms yet with balancing electrons. So, they are a charged plasma. Im...
Kepler's Laws give us the velocity of everything in the debris field and comet cloud-- At any radius, $i$, the velocity of the circular orbits (and a good rough definition of a "belt", although th...
I was researching genomes and observed some similarities with literature that I think might better help communicate the topic. Wanted to share them: There exists an Alphabet (A, C, G, T and some...
I think I've answered here https://scientific-speculation.codidact.com/posts/292119 . I'll re-post for easy access. Setup I realized that it's possible to design a specific box that's bigger on t...
Setup I realized that it's possible to design a specific box that's bigger on the inside. Wanted to write this down. Relating Mass to Lorentz Contraction As velocity approaches the speed of ligh...
Modulation of BBO-Entangled Light Assuming this Video of Entanglement in Action is not incorrectly hiding some additional filter operation, it seems (from the video) that you can quite obviously m...
Orbital rings are a proposed megastructure intended to dramatically reduce the cost to enter or exit a planetary gravity well. The ring is a solid structure, belting around the planet like a hula h...
Utility fog is a swarm robotics concept in which a mesh of robots barely larger than a grain of pollen (5 micrometer ( $10^{-6} $ m ) bodies and 50 micrometer arms) are dodecahedrons (12 sided pol...
Yes. Although this may be streching your definition of oil a bit. The oil product could host some sort of microfauna that cure the product by building EPS microstructures. https://en.m.wikipedia....
Advertise on Gab Gab.com is an environment where very little advertising is happening (so what you spend will be visible), and the audience is almost completely people actively looking for alterna...
