More efficiently than what? Can you show that it is actually possible?

Push gravity hijack from gravity, push or pull
DrKrettin replied to stupidnewton's topic in Speculations
That observation in itself does not give you the right to conclude that Newton's Law is wrong - that is an extremely simplistic argument. What you need to consider is the work needed to transport the flag from the Earth to the Moon, and the change in potential energy of the flag in moving it. I might even be tempted to work out the maths here. But given that the object would be to demonstrate the validity of a law which would have been rejected ages ago if your argument actually had some merit, I'll just leave it to you to collect your Nobel prize. -
But I don't see this. All I see is the box on light blue with a heading "Modred... said" Sorry to be off-topic

Energy is sense of force which governs our reality as such. Like vitality, body functions, movement of atoms ... and those are dimensions that this "energy" as basis governs or moves various dimensions of our reality, experience, emotion and everyday life. Here, I understand what you are referring to. But in scientific terms, energy and force are not the same and cannot be equated. You are using a vocabulary which a scientist will dismiss as meaningless. This does not mean that your concepts do not exist, just that you are not being scientific when describing them. Edit: how can I chop up a post and create two quotations? This formatting baffles me
-
He's not using the terms "energy" and "dimensions" as a scientist would. I've tried having this kind of conversion many times, and they inevitably fail because when the terms differ from scientifically accepted ones, nobody is ever capable of defining what they actually do mean. This makes the dialogue impossible.
-
Fine, but there is no evidence at all that this kind of "energy" you are talking about actually exists. None whatsoever. So why would a scientist want to team up with you?
-
If it is not "The physical one" then it is not what mainstream science calls energy, so give it another name! If lab conditions exist to prove it, then it must by a physical energy. How do you expect to measure some form of "mental energy" in a lab?
-
Mainstream science recognizes energy as a definable and measurable concept. If you want to research something like Qi/Chi, I suggest you either demonstrate that it is a form of energy as scientifically recognized, or you call it something else. The former option will probably result in a Nobel prize.

My first step would be to excavate around where the downpipe drain goes underground. It shouldn't be too difficult to find the elbow which tells you which direction it runs off at. I would be tempted to dig a trench along the line of that drain and find out what provision there is to lose the water. Until you've done that, I can't see much point in suggesting anything else.

A 3-D animation of the cell has been created here, by the Uni of Tenerife, and I wanted to share it. http://fablab.webs.ull.es/project/la-celula/ Note there is an English version

So what exactly is the subject? Whether anything exists?
-
Hard to believe that somebody says that.

Medical Marijuana herp derp
DrKrettin replied to Elite Engineer's topic in Biochemistry and Molecular Biology
There are around 66 different cannabinoids, and I don't think it is clear which ones have specific effects. Would you be able to select one of the 66 out, assuming you knew which one you were looking for? -
Why do flies always try to land themselves in your face in the summer?
DrKrettin replied to james_pain's topic in Biology
My own personal experience is that flies are mainly attracted to moisture. Where I live (Tenerife) the climate is very dry, usually a very low humidity. When I have had a shower and emerge with my head wet, I am tormented by any flies in the house who find it an instant target, and I usually finish up with the absurd attempt at swatting myself on the head for 20 minutes. When I've dried off, they lose interest. They also make a beeline (if I'm allowed to mix insects) for any pools of water, such as in the sink or on a work surface where something has dripped. -

DrKrettin replied to james_pain's topic in Biology
I've found this link to Scientific American where they state that fruit flies are repelled, but mosquitoes are attracted. -
That's not how christianity developed, though. It was utterly vile in the Middle Ages, the Spanish Inquisition is an obvious example of spreading religion by force.

My 8-year old grandson plays the violin. He usually tunes his violin before a lesson, using his teacher's electrical device which measures pitch exactly (you specify, say, middle A and play the note, and the machine shows green if spot on). Yesterday he tuned his violin at home, this time using his mother's identical machine which she uses for singing practice. He then claimed the machine was wrong, it wasn't the same note. This was dismissed as nonsense, but she checked later and discovered that her machine was set to A=440 Hz (Concert pitch in the UK and USA), whereas the teacher's machine was set to A=443 Hz which is standard in Germany (where he and his teacher live). Given that half a tone difference is a frequency change of about 25 Hz at that pitch, I find that noticing a difference of 3 Hz is unusual to say the least. Now I know that the ear is sensitive enough to detect a difference of about 1 Hz when two notes are played one after the other, but this was not the case - he just heard one note in isolation and claimed it was wrong. So my question is this: Is such a sensitivity to pitch plausible?
-
Excellent article, thank you. I love diagram 1. It's a pity that he seems to place trisectors in the same category as those proving Fermat's conjecture. So you never know...

Somebody already has researched the behaviour of bees by having tiny trackers on their heads, so the technology is there. But my budget isn't.
-
Yes - sounds like fun. But there is no information about how these creatures behave, and they are fascinating. They live in dry stone walls and are continually hiding in crevices, so any device such as a cocktail stick would not last long. They seem to have a kind of territory, at least the large males do, and I would like to monitor (pun alert) lizard territory behaviour. Their social behaviour is a mystery, and I suspect the males have a kind of hareem. There is one group which lives in a hole in our house wall, and consists of a large male and female and what are perhaps several offspring of various sizes, or perhaps they are girlfriends. Their favourite food is scrambled egg, but they are also keen on bacon, coldslaw and cheese. They are quite prepared to walk onto my hand to get this.

I have been wondering how to track lizards in our garden, because their movements and habits are rather a mystery. I would welcome information on tracking devices, but they would have to be cheap and weigh less than, say, 1 gram, so I think I'm on a loser here. I haven't even begun to solve the problem of how to catch them and fix the device anywhere safe.

Why on Earth say they are weak? Compared with what? And why stupid? What exactly is the point of life without emotions?
-
I'm all for "making difficult topics understandable" but not at the expense of accuracy. For example, in that link: This “inverse-square law” is quite sophisticated enough to explain .... why the planets travel in an elliptical orbit around the Sun This is quite wrong for starters. It is the conservation of angular momentum which determines that, not the inverse square relationship. He then goes on to talk of the principle of equivalence, expressed as gravity and acceleration being the same force, which is a baffling mixture of dimensions.

Heavier objects actually not falling at the same speed?
DrKrettin replied to Juan Carlos's topic in Classical Physics
Smartarse comment: If they are falling side-by-side, then the larger one will hit just before the smaller one because it has a larger diameter. -
Well actually, ladies and gentlemen, I have to inform you that we did have some chickens which laid bluish eggs, and they were.... drum roll... blue chickens. I jest not - they were Blue Leghorns. Edit: this amazing piece of information has only just occurred to me, but 'tis true. We had them when we lived on a sheep farm, and the chicken used to love eating the maggots they found in sheep droppings. This resulted in the eggs having green yolks, but that's another issue.
