Relativity theory equals e equals mc2?
Yes. It is Einstein's celebrated equation, E=mc2. It means "energy equals mass times the speed of light squared." It tells how to convert mass into energy. Einstein showed through this that mass and energy can be changed into each other.
What does e equals mc spared mean?
Unless this is a joke, I think you mean squared.
e = mc2 is a famous equation by Albert Einstein. Probably the most famous equation of the 20th century. E stands for energy, m for mass and c for the speed of light (a "c" because the speed of light in a vacuum is a universal constant). Amongst other things it tells us that mass is equivalent to energy, and that a small amount of mass can provide a huge amount of energy.
If you are interested just search on the Internet, or in a science book, for "special theory of relativity".
Yes
What is rules governing operations on real numbers?
there's a phrase you can use to remember the order of operations: Please Excuse My Dear Aunt Sally.
it breaks down like this:
P stands for Parenthesis, complete any operations that are in parenthesis (includes brackets, braces and absolute value).
E stands for Exponents, clear any exponents next (includes square roots).
M stands for Multiplication, complete any multiplication problems (from left to right) in the problem.
D stands for Division, complete any division problems (from left to right) in the problem.
A stands for Addition, complete any addition problems (from left to right) in the problem.
S stands for Subtraction, complete any subtraction problems (from left to right) in the problem.
This order of operations must be followed because if it's not then you can come up with all sorts of wrong answers.
For Example: 5+6*2=? or 5 plus 6 times 2
first: Multiply 6*2=12
now you have: 5+12=?
second: Add 5+12=17
Therefore your final answer for 5+6*2=17
What invention did the people blame the formula e equals mc2 on?
The atom bomb, as well as nuclear power in general.
E does not equals mc2 some help?
A re-writing of Einsteins famous equation is E = mc2 Wherre E is energy, m is mass, c is the speed of light (so c2 is the square of the speed of light)
Is mass mater in E equals mc2?
Mass is a measure of a bodies tendency to resist a change in motion, also known as inertia. So, I guess, in a way, the answer to your question is yes, kind of. The more matter a body consists of the more mass it will have. It would probably be best to separate the two terms in your mind and vocabulary tho...
Does e really equeal mc squared?
If your 'e' means energy, your 'm' means mass, and your 'c' means the
speed of light, then yes. That's been proven many thousands of times.
Algebra was invented by the Muslim mathematician Al-Khwarizmi in the book he wrote in 820. Algebra is the Arabic word (aljabr) for "equation", and the word "algorithm" comes from the author's name, Al-Khwarizmi. He is rightly known as "the father of Algebra".
A:The word "algebra" is named after the Arabic word "al-jabr" from the title of the book [al-Kitāb al-muḫtaṣar fī ḥisāb al-ğabr wa-l-muqābala' , (The book of Summary Concerning Calculating by Transposition and Reduction), a book written by the Muslim mathematician, Muhammad ibn Mūsā al-Khwārizmī in 820. The word Al-Jabr means "reunion. In fact, many ancient civilizations developed some sort of algebraic methods of solving problems, as far back as the Babylonians, Diophantus of Alexandria and the Indian mathematicians such as Brahmagupta, but Al-Khwarizmi is considered by many to be the "father of algebra" because some of his techniques on solving quadratic equations are still in use today. He was the first to solve equations using general methods. He solved the linear indeterminate equations, quadratic equations, second order indeterminate equations and equations with multiple variable.J. J. O'Conner and E. F. Robertson wrote in the MacTutor History of Mathematics archive: "Perhaps one of the most significant advances made by Arabic mathematics began at this time with the work of al-Khwarizmi, namely the beginnings of algebra. It is important to understand just how significant this new idea was. It was a revolutionary move away from the Greek concept of mathematics which was essentially geometry. Algebra was a unifying theory which allowed rational numbers, irrational numbers geometrical magnitudes, etc., to all be treated as "algebraic objects". It gave mathematics a whole new development path so much broader in concept to that which had existed before, and provided a vehicle for future development of the subject. Another important aspect of the introduction of algebraic ideas was that it allowed mathematics to be applied to itself in a way which had not happened before.
Isaac Newton was one of the two inventors of what we now call calculus. (And he did start to dabble in alchemy at the end, but saying he spent the rest of his life working on it after inventing calculus might be a stretch. ;-) )
Al-Khwarizmi is often considered the greatest mathematician of all time.
Arabic scholar Al-Khwarizmi (c. 780 - c. 850) visited
India and collected mathematical material for his book
"Ilm al-jabr wa'd muqabalah". He sold his book to the
Romans. The source of the English word algebra was
aljabr which in Arabic means 'the equating'. His name
became the word 'algorism', the old word for
arithmetic. The same word was the root for 'Algorithm'
used in computing. Through his writings, the decimal
system and the use of zero were transmitted to the
west. Algebra was known to Indians long before
Brahmagupta (ca. 598-ca. 665).
Al-Khwarizmi's algebra is regarded as the foundation and cornerstone of the sciences. In a sense, al-Khwarizmi is more entitled to be called "the father of algebra" than Diophantus because al-Khwarizmi is the first to teach algebra in an elementary form and for its own sake, while Diophantus is primarily concerned with the theory of numbers.
Relativity, it's been verified in thousands of experiments over the past 70 years.
No serious question remains, and it's one of the relatively few 'theories' that have
graduated to the status of 'law'.
What specific function does c² have in Einstein's mass-energy equivalence?
Square of the speed of light...
Why e equals mc2 is necessary?
e=mc2 is a constant. so you can use it in a variety of equations without having to do all the math up to that point. basically it helps us measure astronomical numbers. -- (see: avigadro's number for a similar constant with a similar kind of use.)
e=mc2 means this: energy is the same as mass multiplied by the speed of light times the speed of light. this would be a huge number - so it's shortened by saying e=mc2. it's a nickname!!
What does the word squared mean in e equals mc2?
"c squared" means "c times c" ... the number multiplied by itself.
It's supposed to be printed with the '2' as a superscript, looking like this:
E = m c2How does E equals mc2 relate to radiation?
it relates to radiation because they contain electrons which is radiated
What does E equals mc2 do for the world?
I'm sure that it helps the world explain the concept of what energy is, but i could be wrong after all I am only 16 so yea. Well it also explains what energy is made of.
How did scientists apply Einsteins equation E equals mc 2?
They developed the nuclear bomb that converts a small amount of mass to a huge amount of energy
Who coined the formula e equals m square?
The correct formula is E = mc2 (E equals m c squared) and it was coined by Albert Einstein.
You want to know about e equals mc2?
Get a biography on Einstein. Most good ones have all his theories & how they came about. Some are pretty good at putting it in layman's terms.
How do you place the equation e equals mc2 into action?
You can either use a nuclear explosive or a nuclear power station to convert mass into energy
or
you can collide elementary particles at very high energies so that the energy released by their collision is converted to particles with mass.
