Strange Definition and 588 Threads

I don't know where this will end up, but I am going to start it here. A few nights ago my wife and I where watching TV in the bedroom, we turned off the TV and the light over the bed and went to sleep. After a few minutes (maybe five or ten, I woke up and looked at the TV. It was glowing, but...

Does anyone know of a resolution to the bug and rivet paradox? It is outlined here: http://hyperphysics.phy-astr.gsu.edu/hbase/relativ/bugrivet.html#c1 My first guess is that the rivet does not reach the bug, and the rivet's predictions are wrong because it undergoes infinite acceleration...

Strange idea for exotic matter / antigravity I have spent quite some time on an idea I'd like to present here. Before I start, I'd like to make some points clear (due to some reactions I witnessed on other threads): 1. This theory has not been tested in any way, so I'm not trying to present...

What six letter word in the English language contains ten other words without rearranging any of its letters? On that same order, what seven letter word in the English language contains ten other words without rearranging any of its letters? What unusual property do the words FLOUR, TERN...

Some questions concerning strange words: Firstly, some I know myself (mostly trivial) 1. Find an eight-letter word containing 4 G's. 2. Find a six-letter word containing 3 Y's. 3. Find a word ending in 'mt'. (very easy) 4. Find a word containing the combination 'ufa'. 5. Find a...

Whatever applies. I like the taste of sweet, strong coffee while I am eating double aged, extra sharp cheddar cheese. Same coffee and a salty turkey sandwich goes great as well. As a Catholic School kid who went to church every morning for some years, I always liked the funerals...

For some reason, something just came to my mind about a strange result I got when doing a photoelectric effect experiment early this spring. I had "monochromatic" LEDs (I am most suspicious about them) shining into a hole in a "box" that contained the photo sensitive "vacuum tube thing" (the...

Do strange stars exist? Apparently they are denser than neutron stars and consist of up down and strange quarks. But are they theory or reality?

There have been strange number systems used in the past in different parts of the world ... do you know any? :biggrin:

Greetings all, I am getting strange results when solving this trig equation. I seem to be able to calculate 4 out 7 of the correct angles but how do i calculate the others? Maybe my method is wrong... A = theta 2sin2A = tanA, considering identities sin2A = 2sinAcosA and tanA =...

1) Find a function, f(x) which is discontinuous at 1, \frac{1}{2}, \frac{1}{3}, \frac{1}{4} ..., but continuous at any other points. Solution (I have come across, probably wrong and a half): f(x) = { 1 for all real x; 0 for 1/x where x is natural numbers. Can anyone tell me the answer to...

A very strange situation? Normally I keep all of this stuff in the S&D Forum but we seem to have an ongoing and genuine mystery in Italy that reportedly has many experts stumped. Since this story has maintained its status as a credible one for some time now I thought that some of you non-S&D...

I've heard about some small chip of some kind that has termendous cooling power when a current is run through it. Apparently it is a high efficiency alternative to a large refrigerator when it is kept in a small, enclosed area. It's equivalent to something like 10 bags of ice or something, I...

Strange radioactivity question. please help fast! I know this is in the k-12 forum too but i wasnt sure if this is college level stuff or not so sorrie if this is in the wrong forum. And I am not telling u to do this for me, i just want to know some equations and anything that wuld help...

Strange radioactivity question. please help fast! well, this is a strange question that i have to do a presentation on. I thought it would be easy but i can't find any information after looking through 2 major physics books and searching online. I even asked a tutor about this and still...

well, this is a strange question that i have to do a presentation on. I thought it would be easy but i can't find any information after looking through 2 major physics books and searching online. I even asked a tutor about this and still couldn't get any equations i could use. Plz don't bash me...

NEWS.com.au | Woman registered cows as voters (February 20, 2004) Address:http://news.com.au/common/story_page/0,4057,8737423%255E13762,00.html Changed:7:53 PM on Friday, February 20, 2004 I think this woman should be stopped because it is really just too hard to say, "Two all illegally...

Earlier tonight Tsunami's laptop started producing a very high pitched squealing sound. She thought it might be her hard drive - it did sound a bit like a bearing failure - but to me it sounded more like audio feedback; it wasn't, but it sounded much like that. Then, about an hour ago I had the...

I heard they have developed a watermelon that is red on the outside, yellow rind, and a green center. They say it tastes like any other watermelon. I wish people would leave well-enough alone. I don't want green ketchup, either.

I don't get this: "Its empirical formula is C 10 H 17 N 3 S • 2 HCl • H 2 O" What is with those dots? And the middle part has a number before a letter...

can someone tell me what's the physical system of Henon and Ikeda attractor?? or tell me some web side about this, because i need to do an assignment:wink: thank you!

Wolrams story reminded me of one from the National UFO reporting center: http://www.nwlink.com/~ufocntr/ First, this is nothing like Wolram's story in that Wolram's is interesting; this one is kind of funny and sad. I'm not sure when this took place; I read this a few years ago somewhere...

Hi all, maybe this is not the proper forum to post this. Because it rather belongs into a section 'strange effects in everyday life', or whatever. Well. Yesterday I opened a bag of peanuts. The ones that have the closed shells which contain two nuts each. I found the best way to crack them...

Strange Sun-like Object... Any Ideas? A few days ago, my family and I were stuck in a traffic jam on the expressway about an hour before sunset. There were no clouds in the sky and my sister pointed out what appeared to be a small sun a quite a bit to the southeast of the larger one. I have...

What do people make of the following quote, attributed to Kissinger? It reminds me of Ronald Reagan's comments regarding an extraterrestrial threat to Earth(which he made at the UN, around about the same time as this). "Today, America would be outraged if U.N. troops entered Los Angeles to...

According to SR, a photon has an equivalent mass of h / c λ where h is plank's constant, c is the speed of light, and lambda is the photon's wavelength. So, at some point the equivalent mass of the photon should be sufficient to cause a black hole. (Using the simplified formula I...

i was playing with numbers the other day and noticed this - Anything multiplied by 9, will equal 9 when added this is really weird considering that it doesent work with any # i know this belongs in the math forums, but using physics could generate a good theory, it may be stupid but...

f(x) = (1 - x^2)^1/2 This all stems from me approximating pi by numerically evaluating the integral S f(x)dx from 0 to 1 and multiply the sum by 4. Now... Would you agree that f(x) has a derivative f'(x) = (1 - x^2)^-1/2 * -2x ? According to my textbook this is so. Now I can...

Not quite sure where this post should go so I'm putting it here. My wife and I were walking the dog the other night and looking toward scorpio we saw a flash of light and then a very broad "vapor trail" like a glowing stripe crossed upwards across the sky. We walked on further and about five...

So I came across a question in a quiz book the other day and I still haven't been able to answer it, so I figured I would ask some experts... Here goes... As a NASA senior physicist, would you agree with the calculation made by a junior physicist regarding the speed of an artificial...

1/7 = 0.142857142857... 2/7 = 0.285714285714... 3/7 = 0.428571428571... 4/7 = 0.571428571428... 5/7 = 0.714285714285... 6/7 = 0.857142857142... That's strange.

For you statisticians out there, I have long wondered about the possibility of evaluating the "truth" of personal claims by using statistical analysis. Considering the incredible success of demographics and other fields, might this also be possible. If you look at my other threads you will...

makes sense eh?
