  1. Yes but your delivery cost is related to amount you order as well. Using the flawed original delivery price

     

    113.5 miles from A Price = 85*6 + 113.5*5*6 = (85 + 113.5*5)*6 = 652.5 * 6

    114.5 miles from P Price = 80*6 + 114.5*5*6 = (80 + 114.5*5)*6 = 652.5 * 6

     

    Still the same. Your argument would only work if the delivery cost were independent of the quantity - I think that could be a later question

     

     

    "your delivery cost is related to amount you order"

     

    How? it doesn't say that - it says $0.05 per mile

  2. No I don't think it is necessarily cross pollination, because that would involve using seperate species to germinate a new plant with the desirable properties. Using pollen from the same species but from plants within that stock that have been selected specifically because of their desireable traits is more what I meant.

     

     

    selective breeding it is then!

  3. "Two gasoline distributors A and B are 228 miles apart on Interstate 80. A charges $0.85 per gallon and B charges $0.80 per gallon. Each charges $0.05 per mile for delivery. Where on Interstate 80 is the cost to the customer the same?"

     

     

     

    surely the answer will vary depending on the size of the order?

     

    I mean if I order 1 gallon from A at $0.85 and 1 gallon from B at $0.80 the difference in price is $0.05

     

    So the point at which the price is the same from both companies is 114.5 miles from B and 113.5 miles from A

     

     

    However, if I order 6 gallons the difference in price $0.30 so at the same distances the price from A including mileage would be $10.775 and the price from B is $10.525

     

    Do you see what I mean?

     

     

  4.  

    Interesting reading, what if the capillary action was used to draw the water up a slope and the down the other side (not as low as where it started), and then pool up until it poured over the edge onto the water wheel?

     

    Or, use ferrofluid - capillary action draws it upward and a magnet encourages it to form droplets and fall back down?

     

    Sorry to be so persistent with P-motion all the time, I just dont like the idea that it can't be done (it's my pet peeve)

  5. I don't know if it counts but over time I suppose you could use selective breeding (is that the right term for plants?) to produce a strain with properties you desire - I.E larger/More fruit or something that simply grows faster.

     

    You would of course need examples of these plants to breed into something where these particular properties were more prominent.

     

     

    Cross pollination?

     

    People regularly do this with cannabis at home (or wherever).

  6. Who decides what is beneficial or not?

     

     

    Whether or not you survive long enough to pass on your genes

     

    Or, if you will - Life

     

    A creature with a beneficial mutation may be more successful (at finding food, evading predators, surviving the climate...etc...) than one without it.

     

    Conversely, a creature with a detrimental mutation will likely die and not pass it on to the next generation.

  7. The later stuff I mentioned is just a "what if" scenario. But the people we consider to be geniuses did have:

     

    ....inheritance of ideas from written documentation and history, combined with a safe environment in which to explore and ponder knowledge frequently at leisure, and the influence of nurture....

     

     

    True, but imagine we had a way to imediately tell the intelligence level of a person without requiring tests or other culturally or environmentally biased methods - for instance a machine that could take a snapshot of the brain and give an intelligence reading.

     

    I would be willing to bet that people from remote tribes were not genius's (genii'? What's the plural?), in fact I would imagine they would be very similar to most other cultures in terms of IQ

  8. Not necessarily. Just because the water flows up doesn't mean it actually does anything once it gets there. If it's a continuous flow, OK, it's interesting. But if the liquid simply fills in the groove in a manner similar to wetting action (what the article implies) then there isn't any energy to be extracted.

     

    If it can be made to fall onto a water wheel before going back to where it started surely energy can be extracted.

     

    Admitedley the amount of water would be quite small so this would limit the size and speed of the wheel and therefore the energy output, but I'm sure a working model could be built

  9. Why would evolution over design the eye, evolution responds only to need.

     

     

    The first basic light sensing cells (which would have occurred as a result of random mutation) were obviously usefull and were passed on to the next generation. As time went on the creatures with the more sensitive light sensing cells obviously did better than the ones without or with less sensitivity to light, so passed on their dna more often -eventually resulting in the complex eyes we have today - hence evolution at work

  10. So, if it is the case that acquired traits can't be inherited, or can only be inherited if they reach the genes, this means that, homologous organs, which have different no. of bones have arise not because of environment but because of change in genes. What is the factor that has governed it?

     

     

    New traits/mutations arise all the time, beneficial ones get passed on more often than those which are detrimental

  11. A ballistic pendulum doesn't measure energy. It measures momentum. And the beauty of a ballistic pendulum is that there really isn't any calibration required (assuming accuracy of a few percent is acceptable). It's a first principles device... You just do the math.

     

    Yes, but momentum comes from the energy that you put in, so you can extrapolate the amount of energy used to cause that momentum.

     

    In terms of calibration what I'm asking is surely I would need to hit it with a known force to give me an idea of how much force is needed to produce X amount of movement?

     

    Or, are you saying that I should calculate the force required using the length and weight of the thing and produce a scale that way?

     

     

    As for smartphone apps - I'm not really willing to smash up my phone and I very much doubt they are any good

  12. yes, the concentration of nerves in the body, the pain threshold (the point at which you begin to feel pain) and possible nerve damage all are contributing factors in this case.

     

    Another important factor is the tolerance of different individuals to pain. MRI scanning has shown that in people who are very sensitive to pain, the parts of the brain involved in:

    1) feeling the intensity of pain and its location (

    the primary somatosensory cortex)

    2) processing the unpleasant feelings of pain (

    anterior cingulate cortex )

    both show high level of activity. In people who show low sensitivity to pain, these areas of the brain do not show high level of activity.

    So the brain also plays an important part in feeling pain.

     

    "the brain also plays an important part in feeling pain"

     

    Part of conditioning is to teach your brain to expect a certain amount of pain and deal with it, as a practising martial artist for many years if I take a break from training (like at Christmas) I actually miss the residual level of pain that is usually with me (like an old friend) and feel strangely unsettled.

  13. Ballistic pendulum:- Good idea, but how could I callibrate it so that I know how much movement equates to how much energy?

     

    I would need something that generates a known amount of energy

     

     

    High tech is too costly I'm afraid...

  14. Hi all,

     

    How can I measure impact?

     

    I'd like to build something relatively simple that can measure the impact of a punch

     

    It needs to be fairly simple and portable, I thought about canibalising some bathroom scales...

     

    Any ideas?

     

     

  15. What I did was calculated black body radiation using pure numbers and specialized functions.... What does this prove??? Infinity has an end within every known number squared , singularities exist because people "think" it is related to time when it is not, hence 10^3 kilometers = volume = cuboid.

     

    So far, there has been no one that can prove me wrong on this, many have tried to speculate but they neither understand or perhaps really do not want to give this a benefit of a doubt, use the numbers I gave them and compare their own results with their own math knowledge.

     

    Why do I care ?? because scientist make big mistakes, then me and others in this world havto to live with it...

     

    I am no longer waiting for answers, I am now going to give them...

     

     

    The numbers are there, comapre them to your own functions and or equations (which of coarse are based on mathematical "LAWS") , then get back to me if you may. Thanks...

     

     

     

    "Infinity has an end within every known number squared"

     

    And tomatoes are truly the ladder of fructose in the scale of fruitiness (or whatever it was)

     

    "but they neither understand or perhaps really do not want to give this a benefit of a doubt"

     

    Science doesn't do "benefit of the doubt" that would be a terrible way to go about things

     

    "hence 10^3 kilometers = volume = cuboid."

     

    Not sure what you're trying to prove with this...

     

    I mean 10 x 3 kilometers could be a measurement of area but it could not be cuboid (for that it would have to be 10 x 3 x 3 or similar, you need 3 dimensions for volume), and 10^3 kilometers is just a whole lot of kilometers

     

     

    What are you saying?

  16. How'd that work out for him? Would he do it again?

     

     

    He said it ran smoother than diesel and that only used cooking oil would work, I'm not sure where he was getting it all from or why stopped using it (although I think he said something about the law requiring some modification to the car to allow you to do it, which he hadn't done)

     

    It was certainly cheaper and as far as I know, he would do it again.

     

    And yes, very different to water :D

  17. there`s 1000`s really, but common ones...

     

    1. Organophosphates

    2. hexavalent Chrome

    3. Beryllium (dust)

    4. DMSO

    5. Psychotropic drugs

    6. metaloids and Selenium.

    7. Hydrazine

    8. Dishonest Poisons

    9. unpredictable explosives

    10. Acetaldehyde (think Hangovers)

     

    in no particular order.

     

    I disagree wholeheartedly

  18. Exactly, the ultimate "boogey man"

     

    It's a means of control - "do as I say and you will be rewarded (after you die which is convenient as I dont want to have to reward anyone myself) and if you don't then you'll be punished (again conveniently after you die)".

  19. I thought this was the internet?

     

    Is there more?

     

    Now I am confused and frightened...

     

     

    Interestingly, my dad ran his (diesel) car on used cooking oil for about 8 months, it smelled like chips cooking everywhere he went.
