    The Heisenberg Uncertainty Principle

    "A particle can only lose heat by transferring its kinetic energy to another particle (since that's what heat is)." So does this mean if a particle could wander like into a field of nothing but dark matter or some kind of vacuum, then it could not lose its heat? Or would the argument be that...

    The Heisenberg Uncertainty Principle

    Dr. kaku will be on Art Bell Sunday Jan. 22 What can I say but IT'S ABOUT TIME!!! I hope to call in and nail doc about his claims that a black hole cannot be created without the power of the sun. :devil: Cern just might be getting there. Condoloences to Art on the recent tragedy but...

    The Heisenberg Uncertainty Principle

    Seeing through the eyes of a quantum particle. I've wondered what that would be like for a long time. Would it be like determining the state of a quantum cat? Maybe it would see things so weird, the information would be lost in translation. What do you think?

    If matter is made up of energy

    whoa, that's a ton of information for someone looking at this in layman's terms. I'll get back with ya. :cry:

    If matter is made up of energy

    Well if it's a manifestation, we have to ask the trite question "why the difference between solid matter and energy"? I understand differences between things can be based upon different combinations of molecules, atoms, subatomic particles and so on but there's got to be a more intuitive...

    If matter is made up of energy

    Care to elaborate? (i.e. why would space push two objects together; I'm assuming you mean the space between matter is what is pushing).

    Kaku and Cassini

    interesting coast to coast show tonight This show sounds like Dr. Kaku's book, "Visions". Reporter and editor at the Washington Post, Joel Garreau, will talk about how we are engineering the next stage for human evolution through genetics, robotics, and nanotechnologies. Find a radio...

    Kaku and Cassini

    changing the subject... Ramanujan isn't the only one who had an interesting dream, it seems. http://www-gap.dcs.st-and.ac.uk/~history/Mathematicians/Thomason.html While at Rutgers, he put everything in place except for one step ... On January 22 1988, he had a dream in which his recently...

    Kaku and Cassini

    Maybe if we holler and scream enough, he'll visit this forum. :biggrin: I don't know what's going to become of this board- if it will stay as it is or what. It's been disconnected from the Physics Forum which does not bother me in the least. His website's forums have always had enough...

    PF ends relationship with Dr. Kaku

    Well I won't really be shedding any tears. This place is so goldarn busy, I couldn't figure out why Cory and Mike would ever stick his forum over here in the first place. I'm assuming they're too busy finishing college/starting careers to be able to take care of it anymore. I know Dr. Kaku is...

    Dimensions/parallel universe questions

    I think Visions is more a look into the future. It's about future technologies and what we can look forward to in medicine, gadgets, etc. I think Hyperspace is more of a classical book in that it won't "age" as quickly as Visions will. Maybe we don't have glasses with the internet built in...

    Space Ships faster than light.

    Dr. Kaku has amazingly written to some of us over the years, including onthecuttingedge yet he never shows up at the forums. Only once-in-a-blue-moon chats. :grumpy: He's a fast typist but I guess too busy for forums.

    French scientists discover method to change the speed of light.

    Dr. Kaku has often described light as not truly having been slowed down but given more area to move in, so it seems as if it's been slowed. Sort of like if you ride your bike zig zaggy, it will take you a lot longer to get from point A to B than it would if you biked in a straight line. You...

    Parallel Worlds: A Question From Olbers' Paradox

    Interesting webpage. As Dr. Kaku (also excellent at spelling, btw) has explained before, it states that a lot of things are additive, specifically the dark energy over large spaces. The no speed limit to expansion thing really throws me, though. I understand that dark energy is going to...

    Parallel Worlds: A Question From Olbers' Paradox

    Excellent reply. Excellent spelling, might I add. Some people think to be a good scientist or engineer or mathematician, you have to be a bad speller. But Ed Witten is excellent at spelling, so it's a myth.

    Kaku and Cassini

    Other than a handful of chat sessions, Dr. Kaku never appeared (posted) on any of the three previous forums (going all the way back to May 2000 on the Yahoo boards, even though he was registered as a user). I've listened to enough interviews and read enough seminars that I think I could...

    Parallel Worlds: A Question From Olbers' Paradox

    Gosh and I wondered why so many people left this forum. Speaking of editing, you might want to invest in a spellchecker.

    Parallel Worlds: A Question From Olbers' Paradox

    Actually, no, I wasn't joking. Maybe I should give you some background so you'll understand where I'm coming from. Right now, though, I'll address what you said about Crumbles' concern over "getting ahead" of our own light being unfounded. In one sense, it is technically unfounded, yes...

    Parallel Worlds: A Question From Olbers' Paradox

    When you say that the universe was transparent and light moved through space, do you mean that there was no matter, no dark matter, maybe even no dark energy (no spacetime fabric or whatever) for the light to travel through; that space was empty except for light? And wouldn't that be...

    If matter is made up of energy

    An axis? http://www.npr.org/templates/story/story.php?storyId=1040015 Up and down have no meaning in space because everything is "out". I can't make heads or tails of this article about there being an axis in space. Anyone care to enlighten?

    Parallel Worlds: A Question From Olbers' Paradox

    I think what Crumbles is referring to is how is that we are seeing baby pictures of the universe. In other words, if the explosion occured, how can we look into deep space and see the beginnings when (assuming we are looking at photons) light travels outward much more quickly than matter. I...

    Parallel Worlds: A Question From Olbers' Paradox

    You guessed it. There was a PBS special about his book Elegant Universe a few years ago. He really screwed up one of his analogies (where was jumping off a building...I won't go into it). :rolleyes:

    If matter is made up of energy

    So we're being balanced by the after effects of the big bang (dark energy) and by some source of inward pull of gravity?

    If matter is made up of energy

    Okay, center of our galaxy then. Suns are rotating around something so there's a centralized pull. There seems to be an outward push/inward pull to everything (a balance) is what I was asking.

    If matter is made up of energy

    Isn't there only a small amount of dark energy everywhere (compared to the prevalence of dark matter)? And if so, then how does is such a small amount of energy capable of pushing things outward? Kaku says that the nuclear force (the outward explosion) of the sun is what keeps it from...

    If matter is made up of energy

    then what is dark matter made of? Is it made of energy, also (in line with the theory that dark matter is what's causing expansion)

    Transporter Quandary

    What I meant was how do you "convert" it when matter is condensed energy?

    Help with a question

    That's not off topic, it's all about walking on water, isn't it? :smile: False vacuum, that mythbusters episode sounds a bit sketchy to me. Been busy but finally thought about this question a little more. One example which may show that running could cause a footfall to land harder...

    Help with a question

    Yeah, I would think that running on the ice would be the worst thing for breaking the ice, walking would come in second and sliding on the ice would come in third. You might stand on something and it doesn't break or it just cracks but if you STOMP on it (as in running), it's definitely gonna'...
