5,059 Questions
What was one of albert Einstein's idiosyncrasies?
he absolutely hated war, and the development of weapons. at this time in his life he became more interested in politics.
Was Albert Einstein unable to walk or talk until he was six?
albert wasnt able to talk till 4 but he could walk
How did Mileva Maric impact on Albert Einstein's life?
Mileva had an impact on Albert Einstein's life because she helped Einstein to make some theories. Some people believe that Mileva invented the E=mc2 theory and Einstein stole her idea.
Contrary to the above, there is no serious evidence that she collaborated with Einstein on his theories. She twice failed the Zurich Polytechnic diploma to teach mathematics and physics in secondary schools, and there is no authenticated work by her in physics. The stories about her collaboration are based on false information.

No,if you concider that his family immigrated to Italy for economic reasons.
What exact day did Albert Einstein die?
Albert Einstein died on April 18th 1995 in Prince tony New Jersey.
UPDATE: Actually, it wasn't 1995, it was 1955, and the correct spelling of the city is Princeton, NJ. He was 76 years old.
My IQ is 129 what does that mean?
It means that you are in the above average range. One point away from being gifted [: That's what my IQ score is too, a 129. This means superior with only about 6-7% of the population falling in this score.
How old was Albert durer when he died?
Did albert einstein die creating the atomic bomb?
No. How could he die creating a thing he did not create? His one an only connection to the creation of atomic bombs was to put his signature on a letter to FDR warning that the Nazis might be trying to make atomic bombs. He did not even write this letter, Leo Szilard (the inventor of the atomic bomb in 1933) wrote it.
What difficultys did Albert Einstein have?
Albert Einstein faced difficulties throughout his life, including language barriers when he moved to different countries, financial instability, and discrimination due to his Jewish background. He also had challenges in his scientific career, such as facing skepticism and resistance to his theories, and struggling to reconcile quantum mechanics and general relativity. However, despite these difficulties, Einstein persevered and made groundbreaking contributions to physics.
What does E equals mc2 represent?
E=mc^2 represents Albert Einstein's theory of relativity, specifically the equivalence of mass and energy. It states that energy (E) is equal to mass (m) multiplied by the speed of light (c) squared, showing the interrelationship between mass and energy.
In what city did Albert Einstein develop his special theory of relativity?
Albert Einstein devloped his theory in Hitler's crib because he was going to betray the USA, but he found out that USA was cooler than you so he made a man in usa
When did Albert Einstein develop e equals mc?
Albert Einstein developed the equation E=mc^2 in 1905 as part of his theory of special relativity. This equation relates energy (E) to mass (m) and the speed of light (c).
1905 was when the paper about it was published. So he probably discovered it a few years earlier? There doesn't seem to be an exact date or anything.
What is albert Einstein remembered for?
Albert Einstein is remembered as one of the most influential physicists in history, known for developing the theory of relativity, which revolutionized our understanding of space, time, and gravity. He also made important contributions to the development of quantum theory and the exploration of the nature of light. Einstein became a cultural icon for his scientific achievements and his advocacy for peace and human rights.
How did albert Einstein create the light bulb?
Albert Einstein did not invent the light bulb. The light bulb was actually invented by Thomas Edison in 1879. Einstein's contributions were in the field of theoretical physics, particularly with his theory of relativity and the famous equation E=mc^2.
Was Albert Einstein sexually active?
Yes. In fact he was extremely active. He was by far the most sexually active scientist of his time.
Who came up with the formula E equals mc?
I don't know who came up with E = mc, but Einstein came up with E = mc2.
Inevitable
Was it possible for Albert Einstein to use computers?
It is not possible for Albert Einstein to use computers because he has short term memory. But he can use computers with programming which makes him remember about his works.
One of the most extraordinary things
about Einstein's energy-mass equation
is its simplicity. However, we still need to
make sure we are using the correct units
when solving the equation,
and that we understand the answer.
The purpose of this page is to solve
the equation as it is and give some idea of
the huge amount of energy locked up in even the
smallest amount of mass.
The Components of the Equation.If we break the equation E = mc2into its components and write out the terms fully we get:
- E = energy (measured in joules)
- m = mass (measured in kilograms)
- c = the speed of light (186,000 miles per second, or 3 ´ 108 ms-1)
We will now examine each of the terms in a little more detail.
Energy.
Energy is measured in joules (J).
How much energy is one joule?
Not very much really.
If you pick up a large apple and raise it
above your head you will have
used around one joule of energy in the process.
On the other hand we use up huge
amounts of energy every time we switch on a light.
A 100 watt light bulb uses 100 joules of energy every second,
i.e. one watt is one joule per second.
Mass.
Mass is a measure of a body's resistance to acceleration.
The greater the mass the greater the resistance to acceleration,
as anyone who has ever tried to push a heavy object knows.
For our purposes here, we can also think of mass as the
amount of matter in an object.
Mass is measured in kilograms (kg), 1 kg is
about the same as 2.2 pounds.
Note that we haven't said
what the mass is composed of.
In fact it could be anything. It doesn't matter
if we use iron, plastic, wood, rock or gravy.
The equation tells us that whatever the
mass is it can be turned
into energy
(whether it is practical to actually
do so is another matter and will be dealt with in later pages in this series).
The speed of light.
The speed of light is close to 186,300 miles per second
(300,000 km per second). In order to make the equation
"work" we need to convert these numbers into
units that are more suited to our purposes.
In physics, speeds are measured in metres
per second. This is usually abbreviated to ms-1;
that is "metres times seconds to the minus one".
Don't worry if you don't understand this notation.
We could equally write m/s but using ms-1
makes the mathematics easier in the long run. Likewise,
we could either say that the speed of light is
300,000,000 metres per second, or, as is
more usual, express the same figure in scientific notation: 3 x 108 ms-1.
Solving the Basic Equation.Now that we have everything in orderlet's have a go at solving the equation.
We will use a mass of
1kg to keep things simple and I will show all of the workings of the equation.
So, with 1kg of mass (around 2.2 pounds) we get:
Note how the units were dealt with and that
kg m2 s-2 is the same as joules
(a rigorous proof of this is outside the scope of these pages).
So from 1kg of matter, any matter,
we can get out 9 x 1016 joules of energy. Writing that out fully we get:
That is a lot of energy! For example,
if we converted 1 kg of mass into
energy and used it all to power a 100
watt light bulb how long could we keep it lit for?
The first thing to do is divide the result by watts
(remember that 1 watt is 1 joule per second):
How long is that in years?
A year (365.25 days) is 31,557,600 seconds,
so we get:
That is a very long time!
Of course,
converting mass into energy
is not quite that simple, and apart
from with some tiny particles in
experimental situations has never
been carried out with 100% efficiency. Perhaps that's just as well.
Conclusion.We have seen that the equation is very easy to solveas it is and that for even a small amount of
mass a huge amount of energy can, at least in theory,
be released. Other pages in this series show how the
energy can be released in practical ways
as well as using the equation in a more mathematical and physical way.
E = mc2
A huge amount of energy from a small amount of mass.
That is used as a conversion factor between mass and energy.
