340 bce
In 335 BCE, Aristotle opened his school, Lucem. He did not believe the Atomic theory and therefore taught his students that all substances were not made up of atoms but something smaller. He believed that everything was made up of small amounts of fire, water, earth and air.
He didn't "discover" anything. He took a wild guess about what very small pieces of matter were like based on really no tangible evidence whatsoever and happened to be approximately correct if you're not too terribly picky about the details.
Leucippus or Leukippos was a Greek scientist who lived sometime around 450-500 years BCE. He didn't so much "discover" as theorized. He was one of the earliest scientists to come up with the theory of atomism, that everything is made up of particles that cannot be divided up any further. The Greeks called these particles "atoms". His disciple was Democritus.
Yes! The Greek philosopher Democritus, born in 460 B.C., first theorized the smallest possible particle, and called it the atom. Of course, the definition of an atom has changed quite a bit (there is no such thing as a water atom!), and we know that even smaller particles exist, but Democritus was definitely thinking in the right direction.
2000 BC through 1001 BC
A:BC and BCE both mean exactly the same thing and cover exactly the same time period. BC is the older term and simply means 'Before Christ', while BCE means 'Before Christian Era' or 'Before Common Era'.
before common era
The term BC and AD are no longer used in modern dating. The terms are said to be offensive to people who do not recognize Jesus as Messiah. The term BCE stands for Before Common Era and replaces the term BC. Therefore, 4 BCE means the 4 years prior to the Gregorian Calendar.
It means 550-330 years before common era. BCE stands for before common era.
It stands for Common Era, and is one half of a system of measuring time - the opposite is BCE, which means Before Common Era. It is gradually replacing BC and AD as a way of classifying years. The present year is 2011 CE. It can also stand for "Christian Era;" perhaps more accurately. There was no sudden commonality in the world at 1CE.
They are the same thing they mean before Christ.
BCE means 'before the common era' and used to be referred to as BC, simply meaning 'before Christ.'
A millenium is 1000 years long from beginning to end. In terms of the modern calendar, there is no year-long period called year zero, no century zero and no millenium zero. As it is on the standard number line, 'zero' is a point in time on the calendar.So, the year 1 BCE (Before Common Era, or BC for Before Christ) ended on December 31 1 BCE, the day before January 1, 1 AD. That first year started on the previous January 1, 1 BCE.The first century BCE is the entire 100 years ending December 31 1 BCE, and starting January 1 100 BCE.The first millenium BCE then started January 1 1000 BCE and ended December 31 1 BCE.The fourth millenium BCE started January 1 4000 BCE and ended December 31 3001 BCE.It is a little odd. The numbers of the years centuries and millenia go in reverse order, like the number line. But the dates within a given year go forward as usual.
Yes they have I mean you should know
I think it's a book club edition, and I heard that those type of books are smaller in hardcover than they are with the regular editions.
