Freefalling object in airtight container
|
| |
Hi, I'm a noob in physics and all but I have a question: Imagine an airtight box filled with air at 1ATM. the structure of that box has a mass of 2kg In that box there's a piece of metal with a mass of 1Kg that's hanging with a small rope. So the whole thing has a mass of 3kg, right? But assuming the rope breaks, while the piece of metal is in freefall,... more »

High temperature molten salt reactors and ethanol production
|
| |
From an other thread (" New Thorium Reactor - Better than fusion - Will end energy crisis forever - Cheap energy again! " ), I re-post here (slightly changed) I see an interesting potential symbiosis between MSRs, capable of producing clean and cost effective high temperature heat, and ethanol or biofuel production. We all well know that current... more »

MMX-LT-Einstein = discrepancy
 
|
| |
I stated this much earlier but in a different form. It is now time for SRians to answer up to this situation. I am keeping it simple so you SR'ians who do understand SR and MMX please use your full understanding to dub in the scientific expressions that will allow you to confront this situation and answer with your solution if, of course,... more »

Propulsion Applied Scalar Soliton Theory
|
| |
Who cares what people talk about? It's what designers *do* that defines the state of the art w.r.t. advanced propulsion technology, invites others to participate, and establishes laws of science that are some of the most profound natural physical laws, esp. as they apply to the calculus, physics, and medical technology used... more »

Towards an understanding of Usenet: Total Weight of Buy
|
| |
Contributing editors: Yaseen Mamuff, Clive Bork Abstract: Many network experts would agree that, had it not been for permutable epistemologies, the investigation of I/O mass might never have occurred. In this position paper, we show the study of virtual machines, which embodies the essential principles of programming... more »

Natural gas use in US industrial sectors
|
| |
It's quite surprising to me that 7,8 of 97 Quads/year of natural gas in the US are used (in 2002) only in the industrial sector [link] Just curious, for which industrial applications does that natural gas use for? Hydrogen production? High temperature heat for siderurgy applications?... more »

Why the speed of light c is the limit for an accelerated charged particle
|
| |
The speed of light c in a vacuum is the maximum to which an electrically charged particle can be accelerated by an electrostatic field. This may be ascribed to the accelerating force being propagated at the speed of light c in the direction of the field. As such, the speed of transmission of the accelerating force, relative to a charged... more »
