    2014: The Year In Science

    Lasers in Space- It looks like communication in space is changing from radio waves to lasers.

    Mapping the Human Brain- There is a project started in 2013 to map the human brain, and create a simulated brain. I wonder if it will gain self awareness? Please keep in mind this is not PRSI. :)

    Practical Quantum Physics- IMO one of the most impressive breakthroughs which validates the notion of quantum physics for the masses is an encryption system based on the principle that observing something changes it...

    iPhone 6?
    iPad Air 2?
    Surly these are the big technology breakthroughs of 2014!

    Keep in mind, it's not as mysterious as it might sound... ;)

    It changes because interacting with an electron changes its states. The interaction can sometimes make it looks like a particle, other times it looks like a wave.

    Recently however, for the first time, researchers have devised a new type of measurement apparatus that can detect both particle and wave-like behavior at the same time.

    I always find it amazing that they haven't been using lasers for communication before. Seems like a bit of a no brainer? I guess its a lot more complex than it seems.

    I've always thought of a stream of electrons, as a stream of info that could register at multiple locations (be seen) and the quality of the message/info being sent would remain unchanged. But if I understand this correctly, the actual electrons, if they are interacted with, change enough that the different state of those electrons can be detected without effecting the data being sent. Wondering if you can simply explain what change occurs in the electrons? Thanks. :)

    I have to make a drug run (of the legal, prescription drug kind) so I'll have to add more info on this later when I get back in and get a chance to dig through my notes and links on this subject... Meanwhile, here's one brief explanation, which is from this page: http://abyss.uoregon.edu/~js/21st_century_science/lectures/lec13.html

    "The quantum world can be not be perceived directly, but rather through the use of instruments. And, so, there is a problem with the fact that the act of measuring disturbs the energy and position of subatomic particles. This is called the measurement problem."

    Cryonics aren't specifically 2014 bit still rather amazing.

    You and the OP of this thread might have a lot to talk about!

    Ha!

    I'm really interested in freezing ones body and reviving it at a particular date...

    Would be great for cancer patients?

    Radio waves are cheaper to work with and has been working fine.

    Are you resistant to change? :p I read through the list of advantages and it makes sense to me.

    ----------

    Yes, I am familiar with this occurrence, but I find it interesting if a quantitative value could be assigned to how many times quantum material has been measured and if it could not revert to a previous "unmeasured" state on it's own.

    I do not communicate with outer space yet, so I pretty much don't care.

    Finger Print Security Is Not The Future- Popular Science.

    The iPhone is mentioned. Wow! :eek:

    It's because the application is seriously limited.
    You need a straight line of sight.

    There's not many ways to use this in our every days lives.

    Well, maybe, but whenever it is that we've discovered the cure, wouldn't the cancer patient have outlived his/her friends/family? I think it would be sad, being revived, healthy and well, to live in a future world with no one who knows you. What if it isnt for another 30 years? Can you imagine all the changes that will have happened by then, considering the advances we've made since 1984?

    This will surely change the way we build cities! fly paper-airplanes!

    There will be a massive social shock. I agree.

    Thorium Reactors- The Possible Way Forward for Nuclear Power

    [​IMG]

    I'll reference this 2011 Popular Science Article about Thorium Reactors, the wonder material- no melt downs and not easily converted to weapons grade material. In fact China, India and Norway are taking the lead on this design. Why aren't we running with it? A trial in Norway started in 2013. :(

    Great read. Alas, seems the US isn't at the forefront of Science and exploration any more. Pity.

    Well, Bill Gates seems willing to "run with it"... See: Bill Gates Is Beginning to Dream the Thorium Dream (except below).

    "TerraPower, the Gates-chaired nuclear power company, has garnered attention for pursuing traveling wave reactor tech, which runs entirely on spent uranium and would rarely need to be refueled. But the concern just quietly announced that it's going to start seriously exploring thorium power, too."​

    Back in 2010, TerraPower was organized, and began investigating a class of nuclear fast reactors called the traveling wave reactor (TWR).

    I'm not in a place to watch this video at the moment. I wonder how much of the A.I. Is free form versus relying on catchy preprogrammed phrases?

    Seems like we've peaked. :(

    Thanks for the link! Looking at the history of the U.S. In many cases it's government independent intrepeneurs, possibly with government funding who make technology breakthroughs. Look at SpaceX for a recent example.

    Unfortunately, the video doesn't give examples of the conversation. The Eugene Goostman bot used to be online, and you could chat with it via a URL. But I can't find links to it now, so I'm guessing it's been taken offline(?)

    From what I remember about "chatting" with the Eugene G. bot, it appears to have been working mainly with phrases for input/output. It can't really understand the full context of some sentences, since it's not analyzing the content on a word for word level. Every chatbot I've encountered online (or as a standalone program) seems to form its response by picking from a pool (preprogrammed) phrases that it assembles a random subject/verb/object format.

    But, I think we'll have computer programs that actually understand on the word for word level before too long! Actually, we already have at least one AI that's beginning to do so. In the video below Ray Kurzweil talks about IBM AI called Watson, which has the ability to actually read Wikipedia articles. Watson doesn't just look for a few preprogrammed "phrases", Watson understands natural language and can generate hypotheses, etc.



    The Eugene G. bot seems to have been able to past the test largely because users because of the way the judges were "set up" -- they were told he was a 13 yr. old boy that was a non-native English speaker. Ray Kurzweil posted a response online regarding the "passing of the Turing Test". It's a pretty good read, and it cites some example of how (badly) Eugene G. responds to some types of input.

    Back in the early 1990s, I took the code for the chatbot Eliza and rewrote it for use online with a Bulletin Board System (BBS) I was running. I told my users this was a live chat to another BBS system that was run by teenagers. I inserted of a lot of smartass responses into the code, so if the user asked a complex question the program couldn't figure out, the chatbot would avoid the question and respond with a teen angst outburst. This chatbot was good enough to fool almost all people for at least 5-10 minutes, some for 30 minutes. I even had a few users send me messages saying something akin to "This new online chat is great but the only person in the chat room was some bratty kid who was a total @$$%#!^" ;)

    This is pretty cool and much more efficient than The Salmon Truck. ;) Washington State has bought into it.

    The Salmon Cannon!
