Why is math so hard?
Math is a very abstract subject. For students, learning usually happens best when they can relate it to real life. As math becomes more advanced and challenging, that can be difficult to do. As a result, many students find themselves needing to work harder and practice longer to understand more abstract math concepts.

Is it possible to travel back in time?
The Short Answer: Although humans can’t hop into a time machine and go back in time, we do know that clocks on airplanes and satellites travel at a different speed than those on Earth. However, when we think of the phrase “time travel,” we are usually thinking of traveling faster than 1 second per second.

Does the past still exist?
It does not travel forward through an environment of time, moving from a real point in the past and toward a real point in the future. Instead, the present simply changes. The past and future do not exist and are only concepts used to describe the real, isolated, and changing present.
How many dimensions does string theory predict?
What is pi exactly?
Succinctly, pi—which is written as the Greek letter for p, or π—is the ratio of the circumference of any circle to the diameter of that circle. Regardless of the circle’s size, this ratio will always equal pi. In decimal form, the value of pi is approximately 3.14. Measure the circumference with a ruler.
How is PI calculated?
In some ways Pi (π) is a really straightforward number – calculating Pi simply involves taking any circle and dividing its circumference by its diameter. In fact if you search long enough within the digits of Pi (π) you can find any number, including your birthday. …

Time as we think of it isn’t innate to the natural world; it’s a manmade construct intended to describe, monitor, and control industry and individual production.
Does the number pi end?
Pi is an irrational number. As such, it has no final digit. Furthermore, there is no pattern to its digits.
How many dimensions are there?
The world as we know it has three dimensions of space—length, width and depth—and one dimension of time. But there’s the mind-bending possibility that many more dimensions exist out there. According to string theory, one of the leading physics model of the last half century, the universe operates with 10 dimensions.

The 11th dimension is a characteristic of spacetime that has been proposed as a possible answer to questions that arise in Superstring Theory, which involves the existence of 9 dimensions of space and 1 dimension of time.
Is time a real thing?
Time is a prime conflict between relativity and quantum mechanics, measured and malleable in relativity while assumed as background (and not an observable) in quantum mechanics. To many physicists, while we experience time as psychologically real, time is not fundamentally real.
Who invented time?
The measurement of time began with the invention of sundials in ancient Egypt some time prior to 1500 B.C. However, the time the Egyptians measured was not the same as the time today’s clocks measure. For the Egyptians, and indeed for a further three millennia, the basic unit of time was the period of daylight.
How many dimensions are proven?
In fact, the theoretical framework of Superstring Theory posits that the universe exists in ten different dimensions. These different aspects are what govern the universe, the fundamental forces of nature, and all the elementary particles contained within.
