SHAMBO'S RULE

If a number x is a square of another number y then the square of  y+1 is {x+(2y+1)}

EXAMPLE:

10242 =1048576 then [1048576+{(2*1024)+1}]=1050625=10252

What a Fact!!!


  • In Tokyo, a bicycle is faster than a car for most trips of less than 50 minutes!
  • A lightning bolt generates temperatures five times hotter than those found at the sun's surface!
  • Forest fires move faster uphill than downhill!
  • Peanuts are one of the ingredient in dynamite
  • The two-foot long bird called a Kea that lives in New Zealand likes to eat the strips of rubber around car windows.
  • A group of geese on the ground is a gaggle, a group of geese in the air is a skein!
  • Clinophobia is the fear of beds
  • The Earth weighs around 6,600,000,000,000,000,000,000 tons (5,940 billion billion metric tons)

WHAT IS SCIENCE

Science (from Latin scientia, meaning "knowledge") is a systematic enterprise that builds and organizes knowledge in the form of testable explanations and predictions about the universe. In an older and closely related meaning, "science" also refers to a body of knowledge itself, of the type that can be rationally explained and reliably applied.

 In an effort to understand the history of the natural world and how the natural world works, with observable physical evidence as the basis of that understanding. It is done through observation of natural phenomena, and/or through experimentation that tries to simulate natural processes under controlled conditions.

Mass of photon

A  mass of a photon can be calculated by Einstein's equation
E = mc²
m = e/c² 

and 
Energy of a photon = h(Planks Constant) * c(speed of light ) / wavelength
.
so mass of a photon = (hc/wavelength )/c²
m = 6.626*10^-34/wavelength / 299792458
for a light ray of red colour
wavelength = approx 400nm = 4 * 10^-7m
so 
m =( 6.626*10-34 / 4 * 10^-7 )/ 299792458 
= 5.525489236957388701219428275277 * 10-36 kg
for a photon of red colour with wavelength = 400nm

this way we can calculate the mass of any photon with a known value of wavelength or frequency

Das' rule Version 2

any number multiplied by 3,4,5 and the result arranged in ascending order will be a Pythagorean triplet.

eg-  2
2(3,4,5) = 6,8,10 (arranged in ascending order from the starting).

6,8,10 is a Pythagorean triplet.


45
45(3,4,5) = 135, 180, 225

so 135, 180, 225 is definitely a Pythagorean triplet.



NOTE: this rule is also true for 5,12,13

eg

2(5,12,13) = 10,24,26

also 10,24,26 is a Pythagorean triplet

it seems We are not alone

NASA just found something strange!! About 2 BILLION Earth like planets found(WOW)
