This Wiki page I've been editing for months with stuff I've read on the internet. Based on existing science and tech already available in Star Wars, which of these would be challenging for a scientist in Star Wars to create? Try to explain why and you can pick multiple entries. Remember, Star...

After watching Netflix's Better than US produced in Russia. I'm surprised at some of the current technology in Russia. I'm imagining that they were like the 1980s when Ipads were not in existence or TVs were still the Cathode Ray Tubes. What cities have comparable technology like the US New...

Today I read about a seemingly new way of using Xrays that results in images that can be colored and more detailed. https://www.marsbioimaging.com/mars/ See this link for example. I do wonder what would be the major differences or benefits from such technology given modern MRI also has very...

I'm curious how technology education in high school has progressed throughout the years. I graduated HS in '89. While there I had three semesters of programming. Basic on an Apple 2E and RPG 2 and COBOL on an IBM systems 3 mid-range. Punch cards for the win. Please share your experiences.

In the USA, the usual solution to keeping water lines from freezing is to bury them. In cold climates this implies digging deep trenches. (On another forum, a person from Minnesota said water lines are typically buried 7 ft deep.) In the days before modern excavating equipment, were...

Music and the crafting and playing of musical instruments are among the earliest manifestations of science and technology in human culture not directly related to survival. Early drums used for communication also provided rhythm for dance and song. Simple reed flutes and pipes, bone whistles...

I've seen examples where a smart phone apparently used voice recognition technology to eavesdrop on conversations and brought up things mentioned as suggested terms in Google search. I mean conversations that were not phone calls - just ordinary conversations. For example, suppose I am...

I am beginning to teach physics this fall and the previous teacher used Principles of Technology (PT) for a remedial physics course. I have all of the textbooks for this class along with the teacher materials but there is no planning information in regards to pacing, how to use the text in...

I get the basics of green screening. The processing software recognizes a small range of green and can substitute a different image where it occurs. Here's what I don't get: if a subject is standing in front of a green screen, they will have reflections of green. Notice that, in the...

Alright, so I'm a screenwriter and I've come across a problem; scientific accuracy. I'm not very smart in terms of science, so I need a little help. The premise of the story goes like this; A group of NASA scientists send a rover up to Europa. It gives them video footage, and they can control...

Just wonder what other people do to handle the sentimental-value-but-useless decisions. I am attacking my attic this summer, one box at a time. A lot of those boxes are little time capsules, some of them going back years, when some surface or room or other was cleaned off by dumping a bunch of...

Major League Baseball (MLB) pitchers are learning how to make breaking pitches better with technological assists. Strikeouts are frequently attributed to increased speed of fast balls, but it seems that there are more strikeouts from breaking pitches. Pitches that are thrown to curve (like curve...

The FDA approved a new class of hearing devices, BOSE hearing aids as described in this Tech Crunch article: https://techcrunch.com/2018/10/05/bose-hearing-aid-gets-fda-approval/ What's unique is that they are self adjusted via a phone app and don't require a audiologist to perform the work...

I'm wondering how and in what time frame new technologies emerged and found application in the history of science. I could make several examples of those which suddenly and unexpectedly changed the world, but not the vice-versa. In particular, I'm wondering which didn't find an application or...

I'm curious about what sort of technology is used for portable chemical sensing and how expensive or portable it is. For instance, I've occasionally been pulled aside by airport security, and they took a swab, wiped it on some piece of luggage and then as I recall (I didn't pay close attention)...

Hello All, The purpose of my joining the Physics Forums is to request advise on the necessity of agile collaboration among technology, law and medicine to promote common good. I started out as an electronics/computer professional, work experiences certifying wired/wireless products and...

I get a ridiculous amount of gmail every day from my college's student body, but 95% is just students flooding the emails with nonsense ' forum bump' type responses and it's a chore to try and check my emails. --Does anyone have any idea how to filter out or mute responses to future emails?--...

This is what they gave me to help me cast my ballot today in South Carolina. o0)

Hi there, I am currently doing a project involving cold-plasma technology systems. I am struggling to find papers relating to surface-micro barrier discharge systems, and the difference between those and dielectric barrier discharge systems. Any help would be greatly appreciated, however basic.

What is the difference between technology and engineering?

Hi, I am interested in the basics of goalref technology however there is not many material out there. What i want to know is why does the magnetic fields have to be low frequency? and how does it detect if the ball has fully crossed the line? And lastly what is the purpose of the coils...

Hi. This is technically an assignment question, but it's not really a problem that I have to solve. It's more of an investigation so I thought this would be a more appropriate place to discuss it. The question basically asks you to compare the thermodynamic cycle of water in a typical thermal...

I just read a http://www.biotechniques.com/news/biotechniquesNews/biotechniques-365668.html#.WMRA5twan6A about new steps in cyborg generation (combining living tissue with engineered elements). It was in reference to this article, which I did not have access to: Raman R, Cvetkovic C, Bashir...

from what i readed in news articles about smuggling tunnels in the US-mexico border and terrorists tunnels in the israel-gaza border it seems that there is no technology that can detect deep(few dozens of meters) underground tunnels and that there is only technology for detecting underground...

I am kind of introverted; sometimes I do not have the time, but for when I do, I'm aincere about my concerns and my replies. :) I am a third year university student that has trouble , at times, finishing his work.

I know I'm opening weird topics but related to my last topic it came to my mind. What do I mean by inhibit, you know taking patent or taking permission to use its license takes some time and money and if we think in large scale, today, almost every company spends lots of time to protect their...

When we finally solved for quantum gravity. Would it only give us a solution to understanding the interaction in Planck scale quantum and spacetime or would it also give us new technology?
