LOG#233. Electron microscopes.

Surprise! Second post today. It is a nice post, I believe. Usually, we see the world using photons in certain wavelengths. Our eyes can see only a very limited width of the electromagnetic spectrum. The quantum revolution taught us that … Continue reading

LOG#228. The scientific method.

What is the scientific method? There are many definitions out there, but I am providing mine, the one I explain to my students, in this short post. SCIENTIFIC METHOD (Definition, not unique) A (cyclic) method/procedure to gather/organize, check (verify or … Continue reading

LOG#223. Pi-logy.

Hi, there. Today some retarded Pi-day celebration equations (there is a longer version of this, that I wish I could publish next year). Some numbers and estimates for pi-related equations: 1st. Hawking radiation temperature (Schwarzschild’s 4d black hole case). (1) … Continue reading

LOG#222. The New SI.

By the time we will find new physics, we have already redefined the SI in terms of base units and fundamental constants. The definition of the new SI is the next one: the SI is the system in which the … Continue reading

LOG#220. Higgs&Symmetries.

    Why the leaves are green? Why the sky is blue? Why diamonds are hard? The Quantum Mechanics can indeed answer those questions, and even more subtle questions. The Standard Model (SM) is the frontier in our knowledge of … Continue reading

LOG#219. Stranger Planck things.

“(…)Suzie, what is the Planck constante value?(…)” Nice to see the quantum fundamental constant in any series, but only shallowly. The rest was awful Science, and I guess bad advisors (or even null advisors) where considered to the big scientific … Continue reading

LOG#218. Atomic elephants.

Have you ever asked yourself why there is no elephants or humans with atomic sizes? Have you ever asked why Earth is so big in comparison with atoms? Why nuclei are 10000 times smaller than atoms? I will be discussing … Continue reading

LOG#217. The 2 pillars.

Time of Cosmic Voyages https://www.youtube.com/watch?v=xEdpSgz8KU4 This is a long post, despite not being a special post (remember I make one of those every 50 posts). What are we going to see here? A five part post! Part(I). A descriptive prelude. … Continue reading

LOG#216. Asian length units: the list.

Asian units for length: a non-exhaustive list. 1 Chi (China)= m= cm 1 Chi (Hong-Kong)= m 1 Chi (Taiwan)=1 shaku (Japan)==0.3030 m 1 chek = m 1 tsun = chek (Hong-Kong) 1 tsun = cm (Taiwan, China) 1 fan= tsun … Continue reading

LOG#214. Supertranslations.

Surprise! Twice in a day! Yes, I have much to tell yet, alive…Beyond the holographic principle, and things like gravity is Yang-Mills squared or that open strings squared are closed strings, we have had other important development in the theory … Continue reading
