Invention Definition and 68 Threads

I have studied Buddhist teaching for 25 years and subsequently find physics a pleasure. I like to invent things by bringing together all the knowledge I have accumulated from unique sources and my own memory. A long time ago I invented a machine to turn oxygen into water and although I did not...

What are some good arguments against mathematics being discovered (or for it being invented)?

If given the question, I would not have fathomed that the chainsaw device with a continuous 'blade' was originally a medical device from the late 18th century. An effort saving machine for lumberjacks cutting wood would have been my first guess. But wrong. But when one thinks about it, the...

Hi. I've just read that microwave ovens were invented 75 years ago. The article mentions the following anecdote: Apparently, Percy Spencer discovered the heating effect of microwave radiation when a magnetron nearby melted a chocolate bar in his pocket. Is this story plausible, wouldn't you...

I love physics, I’m literarily fascinated and passionate about it. Although I would like to focus on applying physics on real world projects (more than on research or discovery). Like making a better combustion system on rockets, helping build the fusion reactors they’re trying to make, using...

Is the main focus of the physics career discovery, leading invention for the engineers? I mean in the hypothetical situation of the building of a rocket, would the physicist spend their time discovering new ways of making combustion or discovering new materials for a spaceship, and the...

Exokat [catsuit exoskeleton] and Simbot 8.4 {invention idea} I was watching a documentary wherein a lady Quadriplegic was operating a robotic arm direct from her brain, and I thought to myself, what she needs is a catsuit exoskeleton. So I set out to invent one, don’t know why ~ I just like...

I’m trying to figure out how logarithms we’re invented. In addition, what does the calculator do when I want to solve a logarithm. After researching I found out that you could compare an arithmetic progression with a geometrical one, obtaining the principal properties of exponent calculation...

Sorry for the wrong prefix, but it is the most appropriate one that I could have chosen. I have been for long wondering if mathematics would be considered a discovery about the universe or an invention of the human brain. If it is a discovery, then math is the universal language of the universe...

I am an undergraduate physics student and I've been working on a personal research project for almost a year which has turned into a design for an invention. I am waiting on a physics professor and a friend who's a mechanical engineer, both very busy people, to review my design and tell me if...

Ok - I have qualified this question with the word stupid so please go gently with me. Imagine you are talking to a rather stupid child when answering please. My question is about dark matter. Every time I do a search for "proof of dark matter", I get the same answer, which is that using the...

Hello, I have a slightly awkward question: what if someone has a great new engineering/physics project which he thinks might work, however he needs a team of specialists in order to validate it and to assess its feasibility? I've heard that many universities have some kind of "technology...

Let's say you invented something, who would you contact to make it public? Such as appear on yahoo news, or in science news articles? I've been working on a pretty cool robot for several years now and was just thinking that it would be pretty cool if it was shared on news websites. Is it even...

I've had the thought for years that it should be possible to dry damp clothes instantly (or almost instantly): You place them into an airtight container, then pump all the air out. In the vacuum, the boiling point of water drops to room temperature, so the water would all boil away, leaving...

I make no promises: I came up with this idea for a new kind of nuclear fusion reactor. I do not want to give off any clues to how it works so I am going to be as vague as possible. I think it could be a viable means to nuclear fusion becoming... well, breakeven. I have by no means tested it...

well i came on here doing some research on a home project. i would like to know the what the energy output a turbine has and if there is an electromagnet capable of turning off and on quickly while repelinng other magnets, and the amount of energy it would use

I am doing business with a Japanese partner to help japanese people to remain safe during earthquakes which require building a small metallic shelter in their homes, it should stand the destruction during an earthquake. My question, what metal is the right choice? :oldconfused: It must have...

I'm sure you've all seen the Google Doodle of Hollywood starlet Hedy Lamarr. During WWII, she co-invented a method of frequency hopping. I've read articles stating that her invention is widely used in wireless communications today.But was modern frequency hopping independently developed, or...

I don't understand the difference. For example, the goldberg variations compared to the art of fugue. Are these both examples of fugues or are Goldberg variations not fugues. Is there a simple way to understand the difference or even better --to be able to instantly recognize a fugue from an...

Hi, so I learned the definition of a Newton which is Definition of Newton - 1 Newton is the force needed to accelerate 1 kilogram of mass at the rate of 1 metre per second squared. - 1N = kg*(m/s^2) But I'm very curious about one thing What tools did he use, and how could Newton...

Hi i have a physics project due in about a week and need to come up with an invention that relates to physics somehow. I'm so stuck and have been thinking and thinking and still i got nothing! I actually have to build a prototype of my idea so anything doable would be great. Any help is...

First, thank you for taking the time to read this. I need some guidance as I am inventing somewhat of a new edible product. Curious as to if someone can point me in the right direction for the type of chemist I should actually be looking for. At first I was under the impression that it would be...

why nobel prize is awarded for blue led invention even though it was invented before? i bought this blue led 2 years back i.e on 2012,

Hello. I'm only twelve, so my ideas may be flawed,but I would appreciate someone who would advise me about my new invention. I will start with the equations.λ=h/p. The particle wave duality of light is necessary for the function of the solar panel atop the generator. As photons strike this, they...

Hey guys, I have a presentation to do and it's called my dream invention.It's like I will present something that I had dreamed it would happen or be invented but its outside reality, the thing is that we need one article or something many people have thought about. I was thinking to do like a...

Hello physicsforums. I'd like to apologize for submitting such a fool thread. Anyway, I'm in disagreemeent with my friend who thinks it was Nikola Tesla who invented AC, but I insist that it was not him. I tried to google it, but I have yet to find a proper answer. He's like, " My physics...

Hello, I am not sure where I should be posting this, so if this is the wrong section, can a moderator please move it? Right. I have become rather fascinated with the worlds technology and physics. Now, if you've ever heard of lucid dreaming and I'm sure many of you have. I lucid dream...

Hi , I was thinking about this , as you know calculus was used many years before the explicit work of both Newton and Leibniz , it was used the hard way , unrecognized , scattered and buried among unrelated formulas and topics. The golden question is ; what if there is another revolutionary...

I have an idea for an invention and I am trying to work out the circuitry. I need some type of rotary switch or another devise that will be user adjustable and assigned to a given weight, then when that weight is achieved on a scale it turns on a basic LED light. I know its a really loaded...

What single invention between 1775 and 1913 has had the biggest impact on humanity and why? Also it could be a process like say the Bessemer process or a simple item like the lightbulb.

"Invention" Idea - Cheap Room-Temperature Superconductors Now? I propose that if you encase a superconducting material along with liquid helium (or some other coolant) inside a Dewar flask or Thermos and then insert liquid helium, and then cool the superconductor+liquid helium once down to...

Any physics invention for making a super catchy and funny charlie chaplin film?

I had a general idea back in the day dubed "the owie stick". after seeing the movie "district 9", about how the "lightning gun" the main character used would or could work in a real life situation. I looked at it as a big tazer and thought if you shoot multiple conductive darts, one right after...

The new unscripted shows are "Invention USA," in...

Greetings, I had an argument with my substitute Physics teacher about the use of the transistor and how important it is/was. Basically, we were debating whether or not it is important because of the invention or whether it was purely the concept that made it so important. His argument was...

Best invention of the 20th century! I noticed that there is a thread for most pointless invention, how about one for the Best? I will start by saying the transistor, i would like to hear some other views; it's your opinion so you can't be wrong! I will do a poll at the end so even if its...

Hey guys, I just started a networking course and I'm pretty bogged down with information that I'm trying to put into a rational context. From my understanding, networking first began with the telephone line, which is pretty straightforward. You have the sender and the receiver. Then there was...

I recently received a patent on a machine designed to convert gravity to mechanical energy. The patent # is 7770389, also there is a additional patent application. Publication # 20090084106. Both can be viewed at the U.S. patent office.

i want to throughly understand the principle of virtual work. why this principle was invented? "sum of work done by forces is zero". such a definition is very vague for me. can anyone explain?

As I read, this seems to be a tough question, even for Philosophers. Other animals too do some maths concept. A prey understands concepts like bigger/larger/smaller concepts. If the number of predators are higher, it runs away. If it's smaller, it's tries to defend. It's possible that an...

Last time people concluded that 'I proved the law of conservation of energy and momentum wrong by my invention'...but the reality is strictly opposite. If this invention DOES NOT work THEN then 2 laws are wrong. This invention follows all rules and regulation governed by the physics book...
