Special & General Relativity :: RE: Twin Paradox Animation

There is a way to fix this paradox. The act of braking or accelerating is the solution. If it weren't for the acceleration and decceleration, the twin traveling wouldn't know he is moving. The ship feels a force on it while it is accelerating from Earth to c, then a force when it turns around, then another force when it brakes at the Earth. From the point of view of the Earthbound Twin, the ship is moving away to a certain point and returning some time later, taken from from his frame of reference. Now from the frame of reference of the Shipbound Twin, the Earth would suddenly accelerate away from him to c, then it would come to a hault and circle around him and start accelerating back toward him to c, then it would deccelerate as it is approaching him until he landed back on it. We know that the Shipbound Twin feels the acceleration and decceleration of the trip. One big question, does the Earthbound Twin feel the same forces as well? He apparently doesn't. Where the physics breaks down is in the frames of reference that are not in uniform relative motion, ie, acceleration and braking frames.

General Mathematics :: Plotting a sphere using the online 3-D function grapher

Hi,
the equation of a sphere is x^2+y^2+z^2=r^2

so z^2=r^2-x^2-y^2

so z=sqrt(r^2-x^2-y^2)

I used this equation to plot a sphere or even a hemisphere but it gives me something similar to a sphere with curves at the edges.

please follow this url to view the function:

Any help

General Physics :: The construction of the elements

The elements are constructed from hydrogen and have numbers of isotopes far in excess of that which can ever be deterined by experimental observation. We can knowm, for example, that nitrogen has 25 possible isotopes but these will never be observed. If you have a complete discription of a system then descripton and prediction and discovery become the same thing. It is a sceintific fact, which will be accepted in the near future, that our solar system begun with 13 planets. These things are merely a consequence of the paradigm of science, which is a complete description of the process that is the Universe.

General Physics :: numeric symmetry

Everything in the Universe has numeric symmetry with something else. For example, there are 16 types of spiral galaxies and solar systems can have a maximum of 16 planets. Another example is the fact that Helium has 7 naturally occuring isotopes, it requires a combination of 7 amino acids for the construction of biology, and there are 7 possible types of solar systems. Numeric symmetry allows us to make discoveries that would otherwise be impossible. Numeric symmetry is just one of the amazing aspects of the paradigm of science.

Concentration cells and absurdities of modern science

A critique analysis of concentration cell and electrode phenomena is provided at following link:
http://www.elkadot.com/chemistry/Concentration%20cell%20and%20the%20salt%20bridge.htm

In the frame of actual physical chemistry it is found that concentration cell works without a coherent explanation. Further, the actual explanation can be proved to be false using simple chemical reactions able to be performed in any low level school laboratory..
A new experiment able to clarify some of electrode phenomena is proposed.

General Physics :: Corpuscular nature of light book…

Corpuscular nature of light book…

Finally, after a long delay the book related to corpuscular theory of light is ready for publishing.
In the book, quanta hypothesis and the actual wave-corpuscular duality, is rule out.
In short, the proposed theory split the actual electromagnetic domain in two different region:
-radio wave and microwave having a wave character
-IR, VIS, UV, Xray, gamma domain having a corpuscular character.

Principal differences between these two categories are analyzed in the book.
1. radio and microwave are produced as result of a RLC oscillator or as result of a electron or nucleus magnetic moment flip; by comparison photons are produced by electron (or nuclear) transition between two orbits without magnetic moment flip. There is no charge oscillation during electron jump between orbits so a photon can't have an oscillating electric and magnetic field.
2. It is impossible to have a sheaf of electromagnetic waves with closed frequencies traveling into a certain direction; by contrary a beam of photons can be formed by different photons energies.
3. An electromagnetic wave can't carry an angular momentum (in fact no wave can do this), and a discriminatory experiment is proposed.
4. An electromagnetic wave can't produce birefringence, more precisely, the separation of incident wave in other two perpendicular waves after travelling in a medium. There are some papers were birefringence of microwave is analyzed, but, a in this case birefringence means change of phase.!!! By contrary photons beams are producing birefringence and a discriminatory experiment is proposed.
5. Optical activity can discriminate further between electromagnetic waves and photons. Electromagnetic waves are not rotating the plane of polarization when travel through such substances and again a discriminatory experiment is proposed here.
6. An electromagnetic wave can't carry a momentum, and by comparison a photon can carry it.
7. A cooled body does not emit electromagnetic waves (radio or microwave). Under a certain threshold where the IR emission stops, the cooling is made by convection and contact.
8. Two electromagnetic waves with closed or equal frequencies interfere without any problem of ,,coherence". Photons needs this ,,artefact" in order to interfere.
9. Brewster angle, total internal reflection is notions without meaning for a electromagnetic wave. For photons, a commons sense description is provided.

Many experiments and some theoretical considerations, discussed in the book, are posted at this link:
http://www.elkadot.com/corpuscular.html

The book proposes new mechanisms for reflection, refraction and light interference.
Electromagnetic waves decryptions (radio and microwaves) are in working now and this subject will be treated in further books.

benzalkonium chloride is readily soluble in ethanol and acetone. Although dissolution in water is slow, aqueous solutions are easier to handle and are preferred. Solutions should be neutral to slightly alkaline, with colour ranging from colourless to a pale yellow. Solutions foam profusely when shaken, have a bitter taste and a faint almond-like odour which is only detectable in concentrated solutions.
