  1. I would like to see you make this assertion "Science can not test experience because it is not repeatable. ...so the scientific method does not work on experience. " in front of a room full of psychologists. And, sadly we do test to see if people get cancer repeatedly- we don't (often) look at one person getting repeated cancers, but we look at whether or not many people in a group that shows the same behaviour (such as smoking) get cancer. The repetition isn't temporal, but epidemiological analysis is a way of "repeating an experiment" without repeating the experiment.
  2. Acetic acid is used as a solvent for hydrogenations because the reaction is faster than with other solvents. http://pubs.rsc.org/en/content/articlelanding/1938/jr/jr9380000454#!divAbstract There is not enough information in the question to decide what the outcome is. In reality, a mixture of the ester and the alcohol will probably be produced.
  3. OK pedantry alert; the answer is certainly not "less than three". The answer may be "fewer than three". It's also possible that the answer is ill defined because there are (at least) two possible interpretations. You can consider a=b as an equation or you can evaluate it as a calculation and the answer is either [true] or [false]. So if, for example a= 4 an b = 3 then a=b is false and (depending on a whole lot of arbitrary rules) that value may be coded as zero, or minus one (or possibly others). So you could interpret the initial post as saying that the first part of the expression is zero if the second part is equal to the third and the first part is 1 if the second part is not equal to the third part. In which case it's (arguably) not an equation at all. Really, the point is that the post and question are ambiguous.
  4. Hypervalent Iodine isn't the only one to have asked that. I asked essentially the same question and it really hasn't been answered (in spite of MW Research's claims. So... What is this thread for? Is it just a trolling exercise?
  5. So, since their lab seems to be in Boulder Colorado at about 1500 metres above sea level, and most people live in cities near sea level, it looks like they have the world's best clock, but it runs at the wrong rate from the point of view of nearly everyone on the planet. Remarkable.
  6. Cool. given the nature of time dilation with gravity, how good an altimeter s that clock? (i.e. how big a change in altitude, near the Earth's surface, gives rise to a change in the rate of passage of time of 2* 10^-18?)
  7. Actually, you can. Let a beam of sunlight pass through a prism and split into a spectrum. than place a piece of black paper with a slit cut in it in the spectrum so the slit only lets the yellow light through. Then pass that yellow light through another prism. It stays yellow and un-split (assuming you set this up properly). This experiment has been done countless times. There's light in sunlight that is genuinely yellow.
  8. Well, thank goodness for that! Six parts in a million million million just wasn't good enough.
  9. You have overlooked a bit of data so obvious that we have all assumed it without saying we were doing so. I did say something related to it in an earlier post. OK, I apologise for not stating this explicitly before; I didn't think it needed pointing out, but, since you insist: The Fukushima ecosystem is still there. So, what we are saying about that diluted splodge is not "it couldn't cause damage" but two things " it didn't cause (much) damage" and "it won't cause further damage",
  10. You can read the abstract for free. It says "For mild linear shaped charges, width of pulses is about microsecond, and the amplitude may exceed 100 V/m. The results can be referenced for the design of electromagnetic pulse protection for aerospace electronics." And for comparison "Typical electric field strengths measured near household appliances (at a distance of 30 cm) (From: Federal Office for Radiation Safety, Germany 1999) Electric appliance Electric field strength (V/m) Stereo receiver 180 Iron 120 Refrigerator 120 Mixer 100 Toaster 80 Hair dryer 80 Colour TV 60 Coffee machine 60 Vacuum cleaner 50 Electric oven 8 Light bulb 5 Guideline limit value 5000 from http://www.who.int/peh-emf/about/WhatisEMF/en/index3.html
  11. The simple answer is no. There are broadly two groups who say other wise. Those who are just lying in order to get money and those who were (for example) sat in front of a monitor a lot when, by coincidence, they fell ill. Some folks just don't understand coincidence, so they think the monitor has something to do with their ill health. I have some sympathy with the second group who are honestly mistaken. If the first group all dropped dead tomorrow the world would be a better place.
  12. How is this " An average person could easily know of "Bose-Einstein Condensate" because of pop-science shows like NOVA and PBS, or, by googling "coldest material ever" or asking a science teacher "what's the coldest temperature ever made on Earth?" different from " An average person could easily know of "Bose-Einstein Condensate" molybdenum disulphide because of pop-science shows like NOVA and PBS, or, by googling "high pressure lubricant" or asking a science teacher "what's the coldest temperature ever made on Earth?" What's this stuff? http://www.halfords.com/motoring-travel/engine-oils-fluids/grease/comma-cv-lith-moly-grease-500g How do you claim to know that "Learning a specific molybdenum compound from practical use? That likely requires at least one year of chemistry " It may take you a year; other people will vary. Essentially what you have is a list where the sole criterion for inclusion is "Does MWresearch think it fits on this list". Well, perhaps you should compile the list yourself. On the other hand, if you tell us what it is for...
  13. I'm intrigued by a couple of things; firstly, I don't have a degree, never mind a PhD. Secondly, you seem not to realise that, for example, motor bike fans are members of society and will know about Molybdenum. I'm not the one who is out of touch here. It's just that you don't know that lots of people are very well informed about some things. If you think the "man in the street" can tell you a lot about Bose-Einstein Condensates then you are walking down a rather odd street.
  14. It's true that they used a lot of zeolites to bury the Chernobyl site. But they used zeolites for the same reason that it is used as cat litter. It soaks stuff up. Any radioactive material will be stuck in a block of gravel and won't go anywhere. There is a difference between stopping the spread of radioactive material (which any barrier will do) and blocking radiation. The point is that, unless you bury your computer in the stuff, it won't do anything. And yes, you can post links as long as you are not spamming us, but that link is to a site that's tryingt to make money by frightening people. There's essentially no real scientific fact there.
  15. I still think that 10Oz was on the right lines when he said "Consistency and repeatability ". If many independent traditions agree consistently and repeatedly on something, that carries a lot more weight that any single tradition. Ditto for authorities or observations.
  16. Newton chose 7 because it had some mystical significance to him and this went along with his religious beliefs. however the light from a yellow LED or a sodium lamp is yellow. if you put it through a prism it stays yellow, rather than splitting into red and green. The images produced on a computer monitor may be misleading because it only uses 3 colours (GRB) to represent all the colours. the eye can distinguish a lot more than 7 colours and modern spectrometry can split the visible spectrum into millions of different wavelengths.
  17. OK, for a start, you shoot yourself in the foot when you say "You personally may find something impressive, but does the rest of the world?" In doing that you make it clear that any person's list will not reliably agree with anyone else's. You might think that "wood" is a suitable entry for the list; some people would count hardwood and softwoods separately. A boyer might only consider yew worth a specific mention and an oncologist might agree- but for a totally different reason. "Every culture around the world has entire stories about things like rock" Sounds like a truly fascinating read- I must check it out on Amazon later. And when you say "Whether or not you are in touch enough with society to know if Molybdenum compounds are esoteric is not something I can directly help you with. " you make an ammusing assumption that "normal people" don't know about molybdenum. i think you will find it's rather more "street" than you thought. http://www.liqui-moly.de/liquimoly/produktdb.nsf/id/en_1521.html?OpenDocument&land=DE On the whole the list is so subjective that it's like asking someone to think of a number, then telling them they are wrong if they don't come up with the number you had in mind. Perhaps we could return to basics. You started the thread with "For a specific project where I seem to have exhausted most possibilities, " What's the project? If we know that, we can target our ideas better. Incidentally, the "average person" has slightly fewer than two legs; slightly fewer than one testicle; and slightly fewer than one ovary. Have you met many average people?
  18. If people see the video they will be in a position to make that decision. Two things are clearly wrong with it. Firstly the tacit link between these two unrelated concepts "That kind of work is perfect for a homeless person. He likes to be on the street, so he is already street-wise. " and secondly the fact that the second concept ""He likes to be on the street" is somewhere between unsupported and wrong. In the view of several people here (including me) it's offensive. Essentially the problem is that you mentioned homeless people at all. What does it have to do with them? Why not just say " we could pay people to take pictures..."?
  19. It's possible that the zeolite contains naturally occurring radioactive materials and may slightly increase the radiation levels. Almost certainly not enough to matter, but enough to make the original idea a bit pointless.
  20. It seems to me that if police officers knew that the camera would record their failure to attempt to talk down the situation, they might put more effort into it. Similarly, a record of the fact that they walk into every situation aggressively and carrying a gun that will reflect badly on them and give them an incentive to change.
  21. What happened before we invented it?
  22. And who can argue that the structure of Molybdenum blue is anything but awe inspiring
  23. You accept that it's possible that the expectation of payment could prevent justice, yet you still think that expectation is the right thing to do. Any delay is too long. He might very well think that they did. They took the bad guy off the streets; that's very valuable. The reason we pay for policing etc is that we value the fact that bad guys get locked up.
