  1. Well maybe it is, but nobody can deny that mathematics is to nature as words to poetry I have no idea what that means or how it relates to my post. In any regard, people can & do deny all manner of things concerning mathematics and I have no intention of going down any such rabbit hole. Good luck on your essay and inasmuch as it's a writing assignment, keep in mind what's important is how you write and not what you write.
  2. Erhm...the tips are supposed to be proven; not old wives' tales. So if Grandpa counts, don't piss into the wind [or you will get covered in piss].
  3. That phrase is mostly a catchy hook used as a title to an article, though it is an argument made by some folk with disdain for math. (As we all too often encounter here at the forum. As if. ) The author explains: The Unreasonable Effectiveness of Mathematics in the Natural Sciences Wigner in fact concludes the article contradictorily to the title saying, As to the OP and asking for math preceding utility or application I'm still thinking...
  4. I would be breaking in because -of course- I thought I heard someone calling for help from inside. If called to account, hero not villain. Confirmation bias. Security against defeat implies defensive tactics; ability to defeat the enemy means taking the offensive. ~Sun Tzu Such judgments are by necessity, secret. The sound would be nearby simply because the critters are only disturbed to activity when you are nearby. When you aren't nearby, they are quiescent.
  5. Inasmuch as the question 'Can anything fall into the Sun?' has been answered in the affirmative, I think my further discussion of comets is outside the topic of the thread.
  6. No, the dust tail material has its own momentum; it is not tagging along but left behind because it is moving slower than the comet nucleus. The water exits the comet as vapor and along with the other gases becomes part of the ion tail. Water molecules do not remain with the dust tail. Comet tails

  8. Yes; the shed dust continues moving along the path of the comet. I don't quite understand that as yet. It's not clear which planets are doing the steering, but what I get from it is that each time the comet comes in it leaves dust, but each orbit is not identical to others and so when the most recent dust trail coincides with past dust trails we get more meteors. In those clips the blocked portion in effect creates an eclipse; anything passing inward beyond the occulting disk that does not later emerge from the other side has for-all-intents-and-purposes 'fallen into the Sun'. SOHO has 12 instruments, not all of which use an occulting disk. Here's info on some specifics. LASCO specs (LASCO=Large Angle and Spectrometric Coronograph Experiment) SOHO Home: SOHO
  9. To get an idea for how little effect the solar wind has on comet dust one has only to look at the annual regularity of meteor showers. With a few exceptions, the source of the debris we see as meteors during these showers is the dust shed as tails from comets. Year after year, century after century, Earth passes through these patches of dust at the same time of year in the same area of space. For example: Shower Name----Source Lyrids - Comet C/1861 G1 Thatcher Perseids - Comet SwiftTuttle Orionids - Comet Halley Geminids - Palladian asteroid 3200 Phaethon Quadrantids - Minor planet 2003 EH1 A longer list here: List of meteor showers Edit:Formatting
  10. The dust tail trails out [more-or-less] behind the comet and the ion tail points away from the Sun regardless of whether the comet is coming or going. Comet Tail As we have said, a comet that falls into the Sun adds its mass to the Sun. [Period] The moving planets do add a gravitational effect to other orbiting bodies -in conjunction with the Sun - but they do not add their mass to the Sun as does a body that falls into the Sun. The planets fall around the Sun, not into the Sun. Just for general consumption, another article on Sun diving comets: [i'm getting a certificate error for the movie that accompanies the article; YRMV] Full Article: >> Sundiving Comet Storm For many of the comets discovered using SOHO, it is the first and last time they have been observed before they fall into the Sun.
  11. While a bit of an oversimplification, earthquake forces can be seen as acting on a plane when a fault ruptures. The forces obey laws of linear elasticity. See also seismology for descriptions of the character of different waves generated by earthquakes.
  12. This may be true, but regardless of when a body falling into the Sun is vaporized or at what layer it is vaporized, its mass is still effectively added to the Sun's mass.
  13. SOHO has recorded numerous comets falling into the Sun. Since SOHO blocks the disk of the Sun from the camera view in order for the comets to be visible, it's difficult to say to what level they penetrate. Here's the SOHO Gallery page of Sun-diving comets: SOHO Comet Movie Gallery One particular hit was intriguing because immediately after there was an eruption at or near the antipode of the impact. >> Did a Comet Hit Cause an Explosion on the Sun?
  14. By-the-by; have you checked out LRADs? (Long Range Acoustic Device) While a tin foil hat probably won't defend against them, ear muffs might. Can you hear me now? LRAD @ Wiki LRAD Homepage: >> LRAD Corp. PS If it was me on that path and the van unoccupied, I would break into it and see what's what. Little counter measure never hurt. But that's just me. A less sinister explanation would be that your passage was disturbing wildlife beneath the leaf cover. Shrews, mice, snakes, beetles, worms, etcetera.
  15. Good luck then with your hat. One other note is that to concentrate/focus a microwave emission, one would want to use a horn and not a dish. Such a wave guide need not be large as you imply in your opening post.

  17. A new study in Oklahoma, where earthquakes have increased on a grand scale over the past few years, indicates it is not the fracking itself that is causing the quakes, but rather the injection of wastewater into formations deeper than the extraction depth . Inasmuch as the Gatwick area appears to have similar deep limestone deposits suitable for such injection*, it is not a stretch to think the area could experience a similar result to Oklahoma if extensive oil recovery activities are conducted. * Geological Profile of Oil Discovered at Gatwick Seismic shift: Oklahomas earthquakes triggered by wastewater disposal wells Oklahoma quake report @ USGS: >> Record Number of Oklahoma Tremors Raises Possibility of Damaging Earthquakes
  18. I did read that report when you posted it in Frank's thread. So wouldn't you need your entire head screened? Even then, might the signal get in through your neck? Perhaps a tin foil/screen suit. For sure, just because you are paranoid does not mean someone is not out to get you.
  19. Kewl! By all means post the result.
  20. I'd say looped limacon; not dimpled. It almost looks like the loop is a smaller and inverted looped limacon itself. A fractal perhaps?
