What kind of technology will be available in a million years from now? Is the world going to be a better place in a million years from today? Will it be possible to solve chess or have completely self-driving cars and self-driving trucks in a million years from now?

I’ve grappled with this question for many years. There is no way humans can possibly know if technological progression ever hits an endpoint. Some say yes, others say no. Even truly brilliant individuals are divided. I want to believe that technological progression has no end because it...

Hello, Im a student in astrophysics and space technology!

Greetings folks. I have noticed that a lot of people into physics and math tend to use Androids (Samsung, etc), so here is a poll to see if that is true. I like both operating systems, but currently use a lower range Android, but am planning on getting a mid-range Android from Samsung instead of...

Oh to be young again, and living in a community of like-minded souls. I have lost my edge, but I am not lost. I only need a whetstone and to be invited back in. A little Fancy like Reba because my way was self-guided.. It isn't your normal process because this is a story about broken...

Butler attended Boise State University for a year. In 1991, Butler was convicted of assault during his freshman year of college. His appeal was unsuccessful or procedural grounds, as a judge ruled that Butler's defense attorney did not raise the issue in an earlier appeal. The Idaho State...

There is a problem in my technological concept that does not allow the normal development of the plot of the book. It takes place on an ocean planet where being above sea level is absolutely dangerous with the level of technology that exists there. So all combat operations there take place...

Hi, I am looking for an app that converts a checklist to text. The advantage of this app is to save time in writing professional reports. For example, suppose a professional uses a list of 10 possible variables to examine a case but finds only 4 variables match a pre-set quality criteria. In...

Precis of a news report from today's Courier Mail. The University of Queensland clamp technology knocked out because it gave false positives to HIV tests is set for human trials early next year. Scientists have re-engineered the clamp, dubbed Clamp2, so there is no diagnostic interference. CEP...

Ok so I don't know how to post a new thread so I'll post my question here: So I have been developing this balloon technology (the LDH honeycomb) and I've since made changes to it: First, instead of making compressive structures out of rigid LDH honeycomb, I've decided to use tensegrity...

I want to start a serious discussion here about our future on this small planet. This thread is especially dedicated to those of you, who are enthusiastic about atomic energy and energy crisis.

I’m in need of recommendation of a general science book (‘general’ means just a bit of introduction and its application, not going into its detailed theoretical and technical workings) which contains the following topics (though not exhaustive) Space Technology: the basic concept of launching...

Hi! How does progress in semiconductor transistors such as Si to SiC or GaN, MOSFET to FinFET, 10nm to 2nm, etc. improves the performance of a controller such as the ABS, ESP, ESC, ... of a car? And how much is the impact of transistor technology progress on such a controller (compared to...

Okay, dogs have been man's best friend for thousands of years, but today modern technology is in a very advanced level. So probably the devices are better than dogs. Why do people still use dogs when hunting, to rescue people in avalanche or among the ruins of a building after an earthquake, for...

Our ability to transmit and receive audio and video are quite well refined these days. I would understand transmission of the others being niche. But they are virtually non-existent. What would Youtube for touch or taste be like? I can't even imagine it. I think there was once a film that...

IMO IaaS would be the right choice as most of the things you can change yourself rather than depending on cloud.. What do you think?

What are the differences between a degree in chemical engineering and a degree in chemical engineering technology. I think that the main difference is that someone who studied ChemE Technology has more knowledge in chemistry than someone with a ChemE degree. Salary wise, which one pays the best...

When a Mars Simulation Goes Wrong https://www.theatlantic.com/science/archive/2018/06/mars-simulation-hi-seas-nasa-hawaii/553532/ The article came across my desk (computer screen). Human behavior is complicated. I'm more interested in the technical side of space travel, specifically the...

I was wondering if radar is safe, can it detect near objects (lets say 50 feet away) and does it accurately see 3D shapes? I am looking for a technology that could maybe supplement augmented reality in the sense that VR objects can be given GPS locations, but don't know if there is something in...

I am currently obsessed with futurism but I am terrified I will run out of novums to contemplate about. A novum is an idea like “FTL travel” or “Gene splicing”. I was wondering if their is any proof that their is an unlimited amount of ideas that humans can come up with. My uncle was reading...

This discussion relates to another thread on the feasibility of operating a nuclear reactor on Venus. https://www.physicsforums.com/threads/could-a-high-very-high-temperature-nuclear-reactor-operate-in-venus.1003619/ Venus represents a hostile environment with a surface temperature of ~470°C...

Bernard Stiegler said that technology is an evolving organism that never ends as long as their are people; yet as an aspiring futurist; I feel that I’ve reached the limit to all the different concepts for technology. All the futurism stuff is repetitive because their are only so many things a...
