Michael Vogel (heluecht@pirati.ca)'s status on Tuesday, 23Mar2021 19:26:37 UTC Michael Vogel QUarks liegen weit über meinem Verständnislevel. Und jetzt haben Quarks etwas gemacht, was auch die Experten überrascht hat  da es nicht dem entspricht, was das "Standardmodell der Elementarteilchenphysik" erwartet.

🎓 Dr. Freemo :jpf: 🇳🇱 (freemo@qoto.org)'s status on Friday, 29Nov2019 23:03:16 UTC 🎓 Dr. Freemo :jpf: 🇳🇱 NOTE: for those who cant read the below equations (they aren't rendered) you can follow this link to see: http://mathb.in/38381
Here you go a full derivation from the math equations you started with to the one I provided you several times...
axioms (given by you, agreed by physicist):
\[E = {m}_{rel} \cdot {C}^{2}\]
\[{E}^{2} = {p}^{2} \cdot {C}^{2} + {{m}_{rest}}^{2} \cdot {C}^{4}\]
De Broglie's Equation for the momentum of a photon:
\[p = \frac{h}{\lambda}\]
Formula to convert wavelength \(\lambda\) into a frequency:
\[\lambda = \frac{C}{f}\]
Simplify given axioms:
\[{({m}_{rel} \cdot {C}^{2})}^{2} = {p}^{2} \cdot {C}^{2} + {0}^{2} \cdot {C}^{4}\]
\[{{m}_{rel}}^{2} \cdot {C}^{4} = {p}^{2} \cdot {C}^{2}\]
\[{{m}_{rel}}^{2} = \frac{{p}^{2} \cdot {C}^{2}}{{C}^{4}}\]
\[{{m}_{rel}}^{2} = \frac{{p}^{2}}{{C}^{2}}\]
\[{m}_{rel} = \sqrt{\frac{{p}^{2}}{{C}^{2}}}\]
then use de broglie's equation for the momentum...
\[{m}_{rel} = \sqrt{\frac{{(\frac{h}{\lambda})}^{2}}{{C}^{2}}}\]
\[{m}_{rel} = \sqrt{\frac{\frac{{h}^{2}}{{\lambda}^{2}}}{{C}^{2}}}\]
\[{m}_{rel} = \sqrt{\frac{{h}^{2}}{{C}^{2} \cdot {\lambda}^{2}}}\]
Now convert wavelength to frequency...
\[{m}_{rel} = \sqrt{\frac{{h}^{2}}{{C}^{2} \cdot {(\frac{C}{f})}^{2}}}\]
\[{m}_{rel} = \sqrt{\frac{{h}^{2}}{{C}^{2} \cdot \frac{C^2}{f^2}}}\]
\[{m}_{rel} = \sqrt{\frac{{h}^{2}}{\frac{C^4}{f^2}}}\]
\[{m}_{rel} = \sqrt{{h}^{2} \cdot \frac{f^2}{C^4}}\]
\[{m}_{rel} = \sqrt{\frac{{h}^{2} \cdot f^2}{C^4}}\]
and bam you arrive at the equation for the relativistic mass of a photon.
\[{m}_{rel} = \frac{h \cdot f}{c^2} \]

人間失格 (dazai@mstdn.io)'s status on Friday, 24May2019 04:12:21 UTC 人間失格 Coriolis force is an inertial or fictitious force that seems to act on objects in motion within a frame of reference that rotates with respect to an inertial frame.
The mathematical expression for the Coriolis force appeared in an 1835 paper by French scientist GaspardGustave de Coriolis, in connection with the theory of water wheels.
Since the radius of a space colony relying on centrifugal gravity is far smaller than a planet, the Coriolis force is more pronounced. #physics

人間失格 (dazai@mstdn.io)'s status on Friday, 12Apr2019 18:54:15 UTC 人間失格 Entropy must be maximized. The negative #entropy of increasingly complex living organisms must fulfill the requirement of the #physics engine running the universe. Fortunately, life didn't stop evolving at bacteria. Bacteria ARE still around and we need them to survive. On the other hand, Neanderthals only exist as DNA remnants. Perhaps the jump to the next level of #evolution will be so extreme that, to future generations, #humans are more like bacteria and less like Neanderthals. #transhuman
