The aim of this experiment was true Prove the Bohr-Sommer field theory, that the direction of angular momentum of a silver atom is quantised, but experiment give some unpredicted result which was in agreement with the hypothesis of spin that was given later. It is a very celebrated experiment conducted by the German scientists in 1922.</p> Promita Ghosh Copyright (c) 2021 WINGS OF AERO https://journals.wingsofaero.in/index.php/tems/article/view/82 Wed, 16 Jun 2021 00:00:00 +0000 Review of Global 6500 Business Jet https://journals.wingsofaero.in/index.php/tems/article/view/60 <p>This article is about Global 6500 Business Jet.

This pressure difference is than calibrated to give various other quantity including velocity. If we look at the physics of a simple manometer than its fundamental principle is the hydrostatic law which relates the pressure at a given point with the difference in level of the fluid. If density and gravity are assumed to be constant than there is no way we can magnify the vertical level of fluid for a given pressure as per hydrostatic law (Δp=ρgΔh). Hence we search for other indirect method to magnify the readings to increase the sensitivity of the instruments. Here I present four different ways we can apply to amplify the reading to increase its sensitivity.</p> Ajit Kumar Chetry Copyright (c) 2021 WINGS OF AERO https://journals.wingsofaero.in/index.php/tems/article/view/24 Sat, 12 Jun 2021 00:00:00 +0000 Breakthrough in Structural Mystery of Glass https://journals.wingsofaero.in/index.php/tems/article/view/92 <p class="western" lang="en-AU" align="justify"><span style="font-family: Times, Times New Roman, serif;"><span style="font-size: medium;"><span lang="en-US">This article is about the structural mystery of glass and other amorphous solids in general which is solved by the team of physlead by prof.

The wind tunnel we have is a very low speed, open circuit, suction type with square cross-section. Its flow velocity is about 0.03 Mach (i.e. about 10m/s) and this is because of fan limit (we have used 9 inch, 2-blade type propeller with a Brushless DC motor). It is entirely made from stainless steel sheet (1/2mm thick). Sections are joined through rivet joints. Theoretically, our critical laminar flow speed is approximately 0.12m/s. Its total length is 1.9m.</p> Ajit Kumar Chetry Copyright (c) 2021 WINGS OF AERO https://journals.wingsofaero.in/index.php/tems/article/view/23 Sat, 12 Jun 2021 00:00:00 +0000 Davisson-Germer Experiment https://journals.wingsofaero.in/index.php/tems/article/view/91 <p>This article is about the experiment which provided the first evidence of matter waves. In 1927 Davidson and Germer provided the first experimental evidence of matter waves through diffraction of slow electrons, the associated de Broglie wavelength of which is of the order of atomic spacings of most of the crystalline solids. Thus the atoms of a crystal can serve as a three dimensional array of diffracting centers for the de Broglie matter waves.</p> Promita Ghosh Copyright (c) 2021 WINGS OF AERO https://journals.wingsofaero.in/index.php/tems/article/view/91 Wed, 23 Jun 2021 00:00:00 +0000 Lorentz transformation https://journals.wingsofaero.in/index.php/tems/article/view/69 <p class="western" lang="en-AU"><span style="font-family: Times, Times New Roman, serif;"><span style="font-size: medium;"><span lang="en-US">Einstein in 1905, after a thorough analysis of facts and after the failure of aether theory, proposed the special theory of relativity.
