There are some people claiming that there is no scientific evidence that suggests that everyone has their own unique fingerprint, which is important for criminal investigations. Is this true? I hope I posted this topic in the right section.

Do you have any bird friendly buildings around you? What makes them bird friendly? When birds strike windows at great speeds, it’s not because they want to get inside, or are somehow crazy, poisoned or out of their minds on toxic chemicals, but rather its because they see a reflection of an open sky. Most tall buildings in North America have highly reflective windows that trick birds’ vision, and what these creature’ brains perceive as the open sky, is instead a 3/4 inch thick wall of glass. Dead birds liter the sidewalks in big cities. Residential sunrooms and conservatories are equally deadly. Ornilux is ornithologically superior glass which birds percei…

I am not sure of the correct place to pose this question, thus I put it here. Is it scientifically possible to prove something is impossible?

I was wondering if a 3D wire-frame of a person could be used to create a unique ID that could be detected by a holographic scanner and used as a valid proof of identity. This 3D scan could be encrypted with a voice print key (that uses the frequencies most commonly occurring in any individuals speech) to produce a foolproof marker for an individual. The voice print serves as the decryption key. The holographic scanner will re-construct the 3D map of an individual and the concerned person will be asked to speak into a microphone that will sample the individuals speech on the algorithm discussed earlier. This overcomes the possibility of phony ID's and is a …

Sports Wireless Technology DETAILS A wireless three-dimensional target is on the playing field. A player kicks a ball at the target. OPERATION When the ball contacts the wireless target the target should log a score. The score would then be wirelessly communicated to an electronic scoreboard. QUESTION What wireless technology will log a score when the ball contacts the target but not log a score if a foot or other object, and not the ball, contacts the target. (If a foot, and not the ball, contacts the target it does not score a point). I have explored RFID, Near Field Communications, Arduino, Bluetooth, conductive paint, etc and have not found a solution to my …

Hi, There is now serious speculation that in the next 50 to 100 years, technology would have advanced to the level that space elevators could be constructed, by use of an earth to space tether of maybe very advanced nano ropes that are up to a 1000 times stronger than steel. This idea used to be ridiculed by most of the science community in the past as simply an impossible dream, but now many of them are rethinking the issue,that in the future there would be a serious possibility of developing the advanced technology, to achieve, what was previously believed as laughable science fiction.

i think silver and aluminum can reflect electronic wave. but is it possible to make a device reflecting electronic wave or micro wave? it must be big range.

Were there ever any dromeosauridae in Africa? I've found examples of this particular dinosaur genus in Asia, South America, North America and Europe, but not in Africa so far.

I like the way this summary is pulled together. Lots of different issues are summarized, and the focus is broad and data-based. It's called "40 charts that explain the world we live in," and it gives a good sense of where we are, where we used to be, and where we seem to be heading. http://www.washingtonpost.com/blogs/wonkblog/wp/2014/01/15/40-charts-that-explain-the-world/ Here is one of my favorites: What do you think? Anything surprise you, stand out, or cause you concern or joy?

First off I am 15, so I still have a few years before I go to college. I consider myself smart, and get very high grades in school without even having to try. I think I want to be a scientist and know it would take a lot of work to do so. I am not sure what field I want to be in yet, possibly something with nanoscience(I know that covers many different fields). Some things that interest me are creating new materials or power sources that would allow humanity to access the wealth of resources in space more efficiently and much more economically. Maybe even working on understanding how energy and matter work together and discover new ways of containing anti-matter or…

A relative of mine recently started watching History Channel's "Ancient Aliens" show. Many of my friend's acquaintances and relatives have also been watching the show, and now are completely convinced that everything said in it is true. (Oh, lord.) The show relates religion to our ancestors' technological advancements, architecture, culture, beliefs, rituals, and other aspects of their lives, and convinces the audience that the gods they believe in are in fact, actually aliens, and all the incredible things our ancestors have done and discovered are the work of aliens. When I was having a conversation with my relative, he said, "You know, aliens built the pyramids." …

I have always been told to challenge science and that is how scientist make discoveries. All the ideas to regular teachers in science laugh because they said its not relievant. I have two ideas that I think have some kind of purpose that people don't 1. Forces having a Force I've been told it is impossible for forces to have a force ex. Gravity having the action force of speed (Noob at science) I see that if gravity from a Blackhole is strong enough and fast enough to suck in light the action of gravity must be close to speed of light. I know this might sound rediculous but I think gravity must need the force of speed to exist and to function. Because lets…

I read somewhere last year that a scientist, for an experiment, made some glasses that turned his vision upside down. Then after about three weeks of weeks of wearing them, his vision switched, and when he was wearing the upside down glasses, his vision was normal. I want to try that experiment. Does anyone have any ways to make them? Thanks Joshua PS, I am doing this no matter what. Even if you peoples say I shouldn't, I still will. I think that it will make life interesting. Doing this endangers my life in no way, so I will do it!!!

I was looking at this very bad picture from another thread on this Forum. 1 Anyone should know some basic principle of perspective: when a photographer takes a picture horizontally from eye level, the eyes of a person standing upright are approximativaly at horizon level, as shown in the following picture. The rule does not count for the guy in the background: it is a strong indication that it is bad photoshop. 2 If the ground is horizontal all around, all other person standing upright must have his eyes at horizon level, no matter the distance from the photographer. That is because the horizon itself is a line at eye level, by definition. So, if the ground i…

Guys, today I stumbled upon a very interesting facebook post about 'ancient aliens' (Link: https://www.facebook.com/photo.php?fbid=682148158492150&set=a.553678744672426.1073741827.537717429601891&type=1&theater). I have seen a few episodes of the 'Ancient Aliens' series on History TV. Some of the unexplained phenomenons like the Nazka Lines, Crop circles, Statues on the Easter Island really confuse me. So, what's your opinion on the 'Ancient Aliens' theory?

my reputation is very low so please increase it please its very low now

i have some dry corns so how can i make popcorn from them??

The rare conjunction of orbital mechanics, the transit of Venus, was perhaps the most anticipated scientific event of the 18th century. Expeditions set off for the far corners of the Earth, including one by Capt. James Cook who sailed to Tahiti to observe the transit. He went on to discover the continent of Australia where I have lived for the last four decades. Explorers like Cook went in hopes of answering one of the most vexing scientific questions of the day: How far away is the Sun? “This was the big unknown for astronomy 250 years ago,” said Owen Gingerich, an emeritus professor of astronomy and history of science at Harvard. Without that number, much else abou…

I'm doing a science fair experiment, and I need to use copper electrodes to send electricity through the soil. What do I need to connect the speaker wire I bought to the electrode?

So last night we had baked potatoes. My dad noticed one of the potatoes rocking back and forth in the oven. He didn't think anything of it, and came back 20 minutes later and it was still going! Eventually it stopped, but started up again by itself a few minutes later, then stopped again. I did get a video, but I don't think I can upload it here. The only explanation we could think of was the metal pan it was sitting on contracting in the heat of the oven. It gradually rocked more and more violently back and forth and then stopped. I am most definately not a scientist; it's very interesting, but I am far better at humanities! I was hoping some scientists could shed light…

Globally a lot of people eat rice as a part of their staple food. I have felt that I feel sleepy after consuming rice. I have personally observed this and a lot of peoples views have confirmed the same. Can anyone please throw light on this ... What (factors) in rice induces sleep? Is the variety/quality of rice linked to this? Has it been scientifically proven? Does the glycemic load/glycemic index of rice play a role in triggering sleep? What is the mechanism of action of factor(s) that induce sleep? Does the brain need to concentrate on digestion of rice and switches off the other signals which make us lethargic? Please help me uncover the mystery behind thi…

What exactly is the mind ? Our nervous system or an extension of it? What are the attributes of our mind? Euphoria ? Intelligence ? Imagination ? Will the same set of stimuli (in a controlled environment) produce identical mental states? Please advise.

Watching the TV the other day with my partner when I heard her say "Really, we still use steam to generate electricity?" When I confirmed to her that yes we still do, she looked at me dumbfounded, which made me think, "why have we not been able to generate large quantities of electricity without steam?" So I jumped onto the internet and there it was, that word that drives our society these days "Economical". It seems that tech created over 100 years ago is still the only economical way to generate electricity. WHY? How the hell could we possibly create a colony on the moon or anywhere else where water is rare if we still need steam to generate electricity…
