Science & Mathematics - 27 January 2007

I know I've done this before, but I can't for the life of me recall how. Given a change in pressure, a velocity of an air parcel moving across the gradient, and the density of the air, I need to find the distance between the isobars. This is extremely idealized so we're assuming everything remains the same across the gradient.

Any suggestions? I'll play around with units and see if I can figure it out dimensionally but if anyone has any hints that would be greatly appreciated.

Thanks much!

Five years ago quantum physic equations concluded that our G-2 Class Star is far too small to have produced the heavier rare elements found on Earth and in the human body.

This research substantiated that ONLY Blue Supergiant Stars of the B-Class Type and above can produce these heavier rare elements.

Blue Supergiants are extremely hot and fast burning hydrogen stars with a life expectancy of only 10 million years; and at about 9 million years they hyperdialate 100 times their mass into a helium-burning Red Supergiant, a one million year stellar phase that is subsequently followed by a supernova event in which the immense gravity compresses the internal mass of the star into either a neutron star or a black hole, depending on its initial size.

Astrophysicists have recently postulated that based upon calculative frequency of its occurrence throughout the Known Universe that star systems tend to be more so binary and trinary rather than monostellar, that a singular star system is unusually rare; and the conjecture goes on to propose that our Solar System may have a “missing star”.

Ancient cultures such as the Dogon of Mali, Africa have been documented to have had an unusual accurate knowledge of the Sirius Binary, including awareness of the nearly invisible presences of Sirius B, which was not discovered by modern astronomy until 1862. Information of this White Dwarf companion to the immense star Sirius A was handed down to the Dogon from the Ancient Egyptians. In fact, Dogon high priests point to the location of the Sun and state, “that is where Po (Sirius B) used to be.”

Ancient mythology appears to be “cosmocryptography” a symbolic language relaying historical cosmo-cataclysmic events of “stellar interactions”, subsequently responsible for extinction level events and the creation of the Geological Column; and documented by post-catastrophic survivors who were eyewitnesses to the events. The myths suggest a once singular stellar deity (Sirius B as a Blue Supergiant) that received a projectile impact (Comet Metis) that split the star’s photosphere and expelled about 70% of its mass in a mass stellar ejection episode. This event subsequently created the “other gods”, being Sirius A (the “Great Mother Goddess of the Gods”), ten new lesser gods (10 planets, besides the Earth which predated this event), and Sirius C (technically, our Sun, known as the “Great Child God and Hero” that was the last member to be expelled but did not have enough velocity to liberate from Sirius B, and thus established a binary relationship with the paternal star, known as the “Great Father Begetter”).

Furthermore, the mythological record appears to indicate that this former Trinary Stellar System, the Sirian Trichotomy, which is the origin of the “Sacred Triad” in pagan religions, split in half when Sirius B, a diminished star of an F1 Class Type (about 1.5 solar masses), after ultimately reaching the conclusion of its helium Red Giant stellar phase underwent a Nebula Discontinuity Event that created the celestial dynamics that severed the system into two systems.

When the accumulative mass of Sirius A, B, our current Sun and the minimal mass of ten planets is combined into a singular stellar mass, that star would equal the mass of a B-1 Class Star, a Blue Supergiant; the star required to have created the rare heavy elements on the Earth and in the human body.

If it is true that the Sirius Binary is actually our “missing star”, the “missing half” of our Solar System and the above mythological interpretations and cross-supported ancient cultural knowledge is true, then this means all life on Earth had to have emerged, including the intelligent modern human eyewitnesses to the Comet Metis Impact Event, “before” Sirius B, the paternal star, was 9 million years old, for this Blue Supergiant never underwent hyperdialation into a helium-burning Red Supergiant, because it never reached its 9 million year age since the Metis Impact altered the stellar life-cycle of this Blue Supergiant, shrinking its mass into an F-1 Class Star.

How does this affect the Evolution/Uniformitarian Model that stakes its existence on the requirement of 5 billion years before the emergence of modern humans? Quite frankly, I think it completely collapses this hypothesis.

Given the radius of Mt.Everest from the earth's core is 8448 m.

That is:
r = 8448 m

Since:
Fg = G (m1 x m2) / r x r
(where G is the gravity constant 6.67e-11)

This g is equivalent to mass times acceleration isn't it? (F=ma or F=mg)

So that gives me a force in the unit of Newtons.

But then, how do I get the acceleration of that obeject per se (at least even estimate it?)

Please and thank you!

There is a house shared by 3 people and the rent is $ 30/-. At the month end they gave $ 30 to the care-taker of the building to give to the owner. When the care-taker gave the money to the owner, he gave back $ 5 and asked him to give it back to the inmates. Instead of giving back $ 5, the care-taker took $ 2, and returned only $ 3 for them. That means each had to spend $ 9 totaling to $ 27. The care-taker took only $ 2-so it is 27+2=29. Now where is 1 dollar? Can anyone give me justification/answer for the missing 1 dollar?

I know nothing about science ........ dropped it asap at school, and since Tomorrow's World stopped being aired on BBC1 a few decades ago I just have to blindly trust that things just happen!

The answer given was: "

n^3 + 11n
= n x (n^2 + 11).

Since for every n, the product n x (n^2 + 11) is divisible by 6, n^3 + 11n is divisible by 6."

But why? Can someone explain it to me? If possible, please include a few useful sites related. Thanks.

According to this equation, mass is equivalent to energy, and mass can be converted id into energy. But is the reverse also possible? Is it possible to convert energy into mass? If yes,then how (theoretically, as well as practically)? If no, then why?

I'm not joking. I'm not crazy. If it's ok to beleibe in reinarnation, and it's ok to beleive that aliens are visiting earth in UFOs. Then why should it be so crazy to believe that a reincarnated soul can come from another planet. I believe I might be. I feel homesick for another place other than earch. I'm stranded here. The best I can do is try to find others on earth who are from where I am from wherever that is.
