Sometimes I see different times logged for the same post... Why ? Differs if logged in, getting then local time instead of GMT? Also, isn't 12:53 AM supposed to be 00:53 if GMT?

If during surgery, a small portion of an organ -say liver- is severed-off and a minute later is placed back nearly as it was but not perfectly aligned to its original position; will it re-attach and function, heal and work properly or the portion will die/rot/cause trouble ?

Seems the effort is from a couple of years ago, but today, the news mentions an electrodynamic tether designed to generate electricity that will slow down space-based debris and fall to earth burning in the atmosphere. How is that meant to work ? ----> http://www3.nhk.or.jp/nhkworld/en/news/videos/20161201140536917/

When voltage is applied to a resistor, current 'moves' through it, or flows. It flows in the amount the resistor value or resistance allows. Can be a little, can be a lot. Think of a water pipe where the flow is restricted by an obstruction inside the pipe. The obstruction is the resistor. The litres per second is the current flowing, the water pressure applied to the pipe is the voltage. A small obstruction will allow more current or flow of the water trough it. For the Ohm's law formula, the current flowing is the pressure applied divided by the amount of obstruction.

A guy from Spain developed "WIMP" (Where is my phone?) years ago and think sold the software. His site showed on maps the path of the phone for a chosen past time. Edited - found ----> http://www.luisespinosa.com/trackme_eng.html

Heavier objects actually not falling at the same speed?

Not in vacuum, but in the real airy planet, find two very identical balloons and inflate one with air and the other with water to the exact same volume and drop them from a height simultaneously... -
On BBC news today, nearly everyone interviewers to interviewed seemed trying now to bootlick, fawn up, flatter Mr. Trump.

I thought that ciphered messages were the cryptograms that contained numbers. In the eighties, often heard cyphered messages on short wave radio, using groups of four numbers. Isn't hieroglyphics cryptogram the proper name for the thread ? With multiple ways of reading, right to left, vertically, diagonally, snake...

Hi. The intake manifold in my automobile has a vacuum indicator that signals when to replace the air filter. Even my vacuum cleaner has one to signal the flow trough the collecting bag is impaired. I want to install an indicator to tell me when my central airconditioner / furnace needs filter replacement/cleaning. What would be a reasonable figure for the amount of vacuum at the HVAC blower intake to consider it restricted, in need of attention ?

Flywheel storage is already in use in the Falkland islands, paired to wind turbines. Tried to find the manufacturer, only saw this smaller? unit : ----> http://www.bomara.com/powerware/pf2-flywheel.htm

Tune to television news as often as you can. Some channels use personnel chosen by their better-than-typical pronunciation/enunciation.

Can you speculate if hurricane Matthew turns to south east as some prediction models show, and collides with hurricane 'Nicole' in the same area ? Has such event happened before ? What would happen ?

I think we are all standing on top of a huge one, and its core temperature has been hot for many million years, and still works.

Why did white people become more advanced than other races?
Externet replied to ModernArtist25's topic in Politics
The availability of cattle aboriginal to Europe and the corresponding productivity by plowing development and their food, protein, leather yield allowed free time to think instead of hunting/gathering. Thinking instead of gathering all day long developed tools, exploration, trade, industry. The need to save food for winter months also created a need for planning. Other benign tropical areas had it too easy. On the hammock, raising an arm would get a banana all year round with barely a rag for weather protection. No need for firewood either. Having it too easy does not work. -

Exactly ! Well made episodes... ----> https://www.youtube.com/playlist?list=PLhzqSO983AmHwWvGwccC46gs0SNObwnZX -
I do not care about the method how. Just modify my DNA with some from a shark, to renew teeth when they go bad... And from a crab DNA, to regrow a limb if needed.

On earth, fish may behave as there is no gravity, hovering in midwater without sinking. But they stay belly down (because of their bladder?) Would they orient themselves randomly in microgravity ? This picture is not fully showing if yes or not : ----> http://1.bp.blogspot.com/-O3apFdAqUoA/U44CEJ_4IUI/AAAAAAAAb8I/CaCEIntjiDI/s1600/4_20121107.wmv_snapshot_00.30_.2014.05.14_14.35.27..jpg

Hi all. Any clues on where to find figures for magnetic field attenuation trough seawater ? As at different depths/temperatures/paths, will a compass become less sensitive to earth magnetic field ?

Welcome. The amount of effort, time, sweat, tears and money to do such conversion for a novice can be beaten over 100-to-1 by getting a motor from a wreck car boneyard for a couple of dollars. Starter, window actuator, blower fans,... Feeding 12VDC into the stator from the external + terminal will produce no magnetism as there is built-in diodes preventing current. Study how it works first, then for a learning experience go ahead for a chance of frustration. It was made as alternator; and that is what is supposed to be for.

Neodymium Magnet (demagnetising process)
Externet replied to samelt's topic in Modern and Theoretical Physics
There was a Nd magnet for years holding a deflecting aluminium foil for stray ambers on my standalone fireplace wall. It dropped as a dead fly a day the temperature was raised considerably. I cannot tell how many degrees, but that data has to be available on the net. So yes, that is one sure way to turn a magnet into a piece of metal. -
Thank you !. Now I can find them ! Good clues.
