The World of Atom (Part X)

ReferenceA Logical Approach to Theoretical Physics



Chapter 51: Interference Phenomena – Max von Laue (1879 – 1960) Walter Friedrich (1883 – 1968) Paul Knipping (1883 – 1935)
Interference phenomena for X-Rays. Ingenious idea of using the atoms forming the lattice structure of a crystal as a diffraction grating for X-rays of extremely short wavelength. From X-ray diffraction pattern, one can not only calculate the wavelength of the X-rays but also find out a great deal about the structure of the crystal.

Chapter 52: Bragg’s Law – William Henry Bragg (1862 – 1942) William Lawrence Bragg (1890 – 1971) 
The Reflection of X-Rays by Crystals. This research showed (1) that the X-ray emission spectrum of an element is characteristic of that element, and (2) that X-rays can be used as a powerful and precise means of crystal analysis.

Chapter 53: Atomic Number – Antonius van der Broek (1870 – 1926) 
The Number of Possible Elements and Mendeleev’s “Cubic” Periodic System. The number of the place each element occupies in the periodic table is proportional to the square root of the number of scattered -particles.


The short wavelength of X-rays provides greater insight into the structure of atoms.


Sadhguru: His Life

I started looking into Sadhguru only recently, since the end of August 2020. I have been researching on the interface between physics and metaphysics and I find Sadhguru’s responses in this area most insightful. Mostly I am impressed by the clarity of his responses to topics that range from common to  esoteric.  I am, therefore, studying him in depth.

At first I looked him up on Wikipedia. Then I read the book Sadhguru More than a Life (2010, 242 pages) by Arundhathi Subramaniam. This is a very well-written and informative book. Here is quick time-line that may be corrected and expanded upon as I get feedback.

So far my understanding of Sadhguru is as follows:

(1) From his childhood Sadhguru has never been religious. He was not even spiritual prior to having, at age 25, the mind-blowing experience where he could not tell the difference between his self and his surroundings.

(2) Prior to that point his modus operandi had simply been to give his full laser-sharp attention to things that interested him. He was quick in understanding the broad aspects of things and then he focused on details that didn’t make sense to him until he understood them.

(3) He was not interested in schooling. He just made sure that he had passing grades to move to the next class. He was interested in Yoga from age 12 but not from any spiritual perspective. Yoga simply helped him exercise his body and attention.

(4) He was fortunate to grow up in an environment where the food was nutritious and wholesome, the family was stable and caring, and he was allowed to be himself.

(5) His later spiritual approach is holistic in the sense that it focuses on practice of attention and not on thinking. This attention is to be put on both physical and mental health. It focuses on the step by step understanding of what brings about physical and mental health, and its practice.

(6) The major difference between Sadhguru’s ‘spiritual’ approach and Scientology is that Sadhguru’s entire emphasis is on attentive observation and not on messing around with one’s past memories and thoughts.

(7) In my opinion, Sadhguru’s approach may be summarized as follows: Start as broad as possible in your observation of life and situations. Grasp the details without missing anything. Practice on being “your” best in whatever you do.

I find that my practice of SUBJECT CLEARING is in tune with Sadhguru’s approach.

  1. The size of the atom is of the order of 10-8 cm.
  2. The size of the nucleus is of the order of 10-10 cm.
  3. The mass of the atom is concentrated in the “point” nucleus at the center.
  4. The volume of the atom is made up of electrons.
  5. Electrons are in a dynamic equilibrium in a plane around the nucleus.
  6. The nucleus of the atom is positively charged, while the electrons are negatively charged.
  7. The total negative charge of the electrons is equal to the positive charge of the nucleus.
  8. Electrons are in a state of perpetual motion within the atom (like the atoms are in a fluid).
  9. It takes energy to push the electron closer to the nucleus.
  10. A chemical element can have different atomic weights.



  1. The bound electron within the atom is same as the individual unbound electron outside the atom.
  2. Mass of the electron is negligibly small in comparison with that of the nucleus.
  3. The velocity of the electron is small compared to that of light.
  4. Electron, settled in a circular, stationary orbit around the nucleus, can be treated by ordinary mechanics.
  5. Passing of the systems between different stationary states cannot be treated by ordinary mechanics, but by emission of a homogenous radiation, per Planck’s theory.
  6. During the binding of the electron a homogenous radiation is emitted (equal to half the frequency of revolution of the electron in its final orbit).
