Elementary concepts from general physics and thermodynamics have been used to analyze rocket propulsion. Making some reasonable assumptions, an expression for the exit velocity of the gases is found. From that expression one can conclude what are the desired properties for a rocket fuel....
Since the rocket stove is awood burningcooking stove, obtaining fuel while on a camping trip is easy. Unlike a campfire, the rocket stove will function very well using small branches and limbs that tend to litter the floor of the woods. This means there is no need to chop larger sections...
The rocket is made of stainless steel, a material Musk is particularly fond of due to its relatively low price. Unlike NASA's SLS, which flies on super-chilledliquid hydrogen and oxygen, this beast is fueled with 10 million pounds of liquid methane and oxygen. The new fuel can be stored...
This rotational force is also used to simulate the acceleration of a space launch for astronaut training. When a rocket is first launched, it is so laden with fuel and oxidizer that it can barely move. However, as it ascends, it burns fuel at a tremendous rate, continuously losing mass.Ne...
What is Ether? Ether is the fuel for the Ethereum blockchain. Although the term Ethereum is often used to describe the cryptocurrency of the Ethereum network, ether is the actual currency used. Ethereumtypically refers to the blockchain, protocol, or network. ...
Neutron stars are created when massive stars reach the ends of their lives and are composed of the densest matter in the known universe.
Nuclear waste is primarily composed of the atoms that are left over after larger atoms are split in a fission chain reaction. This page explains what it is in detail, what the hazards are, how we store it today, what the long-term plans are, and how much
Almost all the medium in interstellar space — about 99% — is composed of gas, with just 1% being in the form of dust and ice particles. Even though the dust component is minor, it can have a dramatic effect that astronomers call "reddening", or at its most severe, "dust extinction"...
My favourite sequence, of a really fast trot with many airborne periods. I cringe a little at how simple this work is, but there’s still great value in observation and a “data paper” as I regarded this one. Still, I like it and it fills a lacuna in our understanding, and takes ...
