When we time travel into the future near the spead of light and four years pass on board ship while 300 pass on Earth, the ship returning to Earth will have to meet the Earth where it will be in 300 years even though only four passed on board ship. It seems the same rule should apply to the past if there was such a thing as the technology to travel back.

Nitrogen is not an inert gas. It just is not usually very active at room temperature. Nitrogen is replaced in deep sea diving by inert helium because nitrogen can dissolve in the blood to toxic concentrations under pressure. Also it can reform as bubbles in the blood when pressure is removed. Helium does not have this problem.

I didn't do it, at least I didn't get caught. Somebody else is responsible. That still doesn't mean we aren't all stuck with fixin the whatever.

I went to google and typed in "spectral of propane"

This is one of what I got.

Is this what you ask for?

I used to putz with chemistry back when I was 10 and would be able to get all sorts of chemicals in the early 60's you can't get today. I had a bunch of formulas I sent away for in the back of a comic book. It cost me a dime for about five pages.

My favorite was pouring pure iodine crystals into a jar of concentrated ammonia and then collecting the sediment. We would fill gelatin capsules with flour and put a dab about the size of a pencil tip of the sediment in the middle of the capsule and close it up. After 24 hours the sediment was dry enough that if you tossed the capsule it would explode in a cloud of flour dust. If you waited 48 hours you couldn't jiggle them without them going off. Also you could paint the sediment on a doorknob or shed lock or rarely used outhouse seat. After it dried, anybody touching it would get a nice flash and nasty purple stain.

I never shared the formula and wondered then why the hell they let us kids know this.

Good thing it was only in my hands cus I was mature enough to know how to abuse it wisely.

Here is a sample of some cell specs. To ge 1.5V your looking at about 25"sq. and I don't know what weight the cells add.

Lots of motors on google search but you can go to a store and buy a toy just for the motor and free gearing if you want one quick.

This one is for SETI fans.

I'm trying to take the intuitive approach and when I see a ship travelling near light speed parallel to me at a distance that allows more than a couple of seconds of observation, I need to see the time dilation effects at the same time.

I had it backwards in my last post. A radio communication from me to the ship would seem high energy and compressed to them and a message from them would be red shifted. Still the radio signals would both travel at the speed of light and contain the same total energy as when they originated.

Intuitively then to me observing, a phaser shot into a mirror ahead of the ship would still travel at the speed of light but be less energy and longer duration after it arrives but it would still total the same energy as when it was fired.

Is this close to what would really happen?

Invest in a static guard wrist strap and attach the ground clip too for when yer putting the boards in. That way you can be sure that if it has glitches, it wasn't you.

Just aman

Because of time dilation, wouldn't a message sent from a ship near light speed be high energy and very compressed?

Maybe a computer could decipher it.

I just found this site if you want to calibrate yer counter.

That reminds me, in what "time frame" would the universe have been created if time is a product of the universes creation, ie how could the superstring multidimensional membranes collide if there is no time? Or is time an arbitrary concept? Come to think of it, how could the membranes be multidimensional if dimensions were a result of the universe?

 

Or did I totally mess that up?

 

If time is a dimension, end of story, we should be able to manipulate our place in it, which brings me back to my idea of temporal momentum.

 

If time is a dimension, we should be able to measure and compare it using vectors (I guess that's velocity).

If we wanted to consider time relative to dimensions we might have to consider phase.

Our best instruments can measure snapshots of time in attoseconds. If our reality was presented to us in slice increments of 1 attosecond I don't think we would notice any difference from what we experience now. That leaves a lot of room for other information.

I like the example of the movie "Contact" where the signal received was a pulse. On the pulse was video and audio and sandwiched in that was a library.

Maybe the key to our phase is Pi mathematically and the key to other phases would be a totally different constant

How about 1 attosecond divided by Pi for our phase.

Yoops it's late and I'm ramblin but I just was pondering phase and maybe this might work as an example of other potential dimensions.

Does the ash still have some combustion going on it as it rises. That would give it lift underneath. If it floats after consumption then I would expect it was consumed down to a structure kinda like buckyball, mostly air and simple form. The rising heated air would carry it easily.

Just aman

I wonder if putting your geiger counter in a bag full of helium would protect it from the effects of the ionization of the air.

Just a thought.

In the Pop Sci archives a guy shows how he puts lead in a ceramic bowl on top of whetstone bricks and the heat from the stones melts the lead. He melted tin also but could only get silver to radiant hot.

I woulda traded my first wife for a garage to work in, time to fiddle, and access to great junk when I was a pup. Because I didn't have it I hurt for how much the world was denied. I think you all know how I feel. I gotta appreciate what was accomplished under ones own roof. Five stars.

Gotta appreciate blowin up microwave ovens too.

It's surprising with all the metalworkers we don't seem to have incredible new garage alloys, or chemists creating something spectacular in their back rooms.

I guess all the easy stuff's been discovered and we're getting in a rut. Still if yer in a rut aim high , like to the edges of the rut, even though somebodies already rode there.

We breath a majority of nitrogen but probably could replace it with another inert gas all our lives and never know the difference. Put some ether or nitrous oxide in it and then it's a drug.

I needed a rectal thermometer for my ex-wifes frig. All her cooking tasted like crap. If it was brown it was vegetables and if it was green it was meat. I survived and am happily married with a great cook wife now. Good luck keeping yer foods the right color.

Since audio sound generally needs a gas carrier to your ears it wouldn't be found in space. The sound on the hull of the ship would be other waves carried and translated by the ships hull. If you want to hear sound and allow for translators then pointing microwave antennas and translating into sound should let you hear the whole event.

The bars are only in the passage between strobes so you wouldnt see a thing. It could be synchronized to look like a solid wall if you wanted to by shortening the chain and changing the phase. Our eyes are pretty inefficient and easily fooled.

Just aman.

Synchronising is pretty simple since the motor would be on the same 60 cycle power so it shouldn't drift out of phase. Kind of like a table saw blade under flourescent lights, you can't tell if it's spinning except for the sound.

The sound could probably be minimized below the noise level of a common escalator because the motor and gearing would be even more remote. Piece of cake.

Thanks YT, blike probably has plenty of scrap microwaves from past experiments and now you give him something else to play with.

I guess we'll be reading about mysterious fires breaking out all over his campus.

I still like the visual demos of physics so we gotta make sure blike doesnt blow himself up.

Doesn't shaped charge technology depend a lot on the containment materials? Reading about material strength, I wouldn't be suprised to see detonators shaped inside fabricated beetle exoskeletons.

What if the bar was tipped leading edge away and maybe rubber rollers on the top near edge? Then maybe it would just hurt really bad. I see it would be easy to make it lethal but hard to design it benign.
