Time Dilation The Theory of Relativity is hard to grasp at times, but one of the strangest aspects of it is Time Dilation. As speed increases to the speed of light, time increases to infinity. Strange, but true. |
Sir Isaac Newton Sir Isaac Newton changed the way the world and universe were viewed in the 1600s. To form his theories, he invented Calculus, and formulated this famous formula for gravity. |
Transit of Venus Mark the Transit of Venus on June 6th 2012 with this design that shows what the view will be during the transit. It's the last chance to see Venus transit the Sun for 105 years! |

Licensed to Integrate You never know when integration of a function can be dangerous -- better leave it to a licensed integrator! |
Pythagarus' Theorem Around 500 years BC, Pythagoras was able to prove that the square of the length of a right angle's hypotenuse was equal to the square of the length of the other two sides. |
Euler - Pure Genius Leonhard Euler was a genius. He made contributions in Mathematics, Physics, Optics, and Astronomy. His famous formula in 1748 relates e, i, pi with 1 and 0 -- pure genius! |
|||
Euler's Formula Leonhard Euler was a genius. He linked complex numbers, e, and trigonometry in his famous formula over 250 years ago! |
Pi Day - Be Irrational Just as Pi is an irrational number, Pi Day, March 13th gives everyone a minute to be Irrational: 1:59 both AM and PM! So take full advantage, and be irrational at 1:59 today! |
Pi Day - Take a minute Not only is Pi irrational, but Pi Day is irrational as well! So, take a minute (March 14 at 1:59, AM or PM), and celebrate irrationality! |
|||
Pi Day - Totally Irrational! March 14th is Pi Day, and 1:59 is the moment in time that lines up with Pi. You've got to admit that it's totally irrational! |
|
Heart Some people think that mathematicians are dull and boring, but you can show everyone that you have a heart, and know how to plot it as well! Just in time for Valentine's Day! |
|||
Math Professor Watch out! Math professors can be dangerous! Will all of that ring theory, fourier series and quantum complexity, nothing gets past a Math prof! |
Math Teacher Watch out! Math teachers can be dangerous! You can't shortchange them, or fool them with math mumbo jumbo! |
Mars Mars, the Red Planet, has been known for at least 3500 years as a "wandering star" and today it is known much more intimately from the mapping from space by the Mars Global Surveyor orbiter |

The End of Time Epoch time started on January 1st, 1970, and it's 32-bit lifetime ends on January 19th, 2038. BE PREPARED. |
Math Connaisseur Not everyone is a true connaisseur of Mathematics -- only the select few who truly appreciate the elegance of Math equations. |
Earth Earth, the third planet from the sun, with a surface of liquid water and land has only a very thin atmosphere as shown in this stunning photograph from the International Space Station. |
|||
Daemons Most people think that daemons are evil, but if you use *nix operating systems, they're great! |
Crazy Mathematician Every Math faculty or High School has one -- a crazy Mathematician. Sometimes they're in the Stats department, or in Pure Math. Working with groups and rings and complex numbers has that effect! Th |
Venus Venus, nearly the same size as the Earth, is both closer to the sun (0.72 AU), and it has an atmosphere of 96% Carbon Dioxide, making it's surface a blistering 460 °C. Nice to look at from space, awf |
|||
I Speak Hex! Hex dumps look horrible to most people, but to computer scientists, they're a gold mine of information. Whether you are looking for telnet control characters or carriage returns and line feeds, hex d |
Never Drink and Derive Make a bold statement about the dangers of drinking and deriving! Mathematicians never drink and derive! |
Mercury Mercury is the inner-most planet, averaging only 39.5% of Earth's distance from the sun. It is also the smallest planet. This beautiful image was taken by the spacecraft Messenger. |

XON/XOFF! Say XON to the world that you're walking towards, and XOFF to the world you're leaving with this great shirt! |
Do the Math! Need to figure things out? Are you trying to balance a budget or choose between buying or renting? The answer is clear: just DO THE MATH! |
Moons of Jupiter by Galileo Quick! What four moons of Jupiter did Galileo discover? It was one of the most significant discoveries in the history of Astronomy! |
|||
It's Complex! What's the square root of negative 1? It's not a real number -- it's imaginary. Most of all, it's hard to explain because it's complex! |
Fermat's Last Theorem Fermat's Last Theorem kept mathematicians looking for a proof for 358 years, until it was solved in 1995. |
Planetary Orbits by Kepler Nobody could figure out a formula for the orbits of planets, before Johannes Kepler thought of an ellipse in 1605. It worked for Mars, and in 1609, he published "Astronomia nova" with his results. |

Saturn and it's Rings Do you know who first saw Saturn's rings, or who found gaps in the rings? Take a look inside! |
|||
Pi Day, 3/14 Celebrate Pi, the ratio of a circle's diameter to it's circumference. It's one of the most important constants in Mathematics and Science! |
Pi - Totally Irrational Pi -- such a simple concept, yet it's a number that cannot be represented as a fraction a/b, where a and b are integers. That means it's Totally Irrational! |
Gravity by Newton Sir Isaac Newton revolutionized astronomy and physics with his formula for gravity in 1687. |
|||
Phi - the Golden Ratio Phi, the Golden Ratio, was used in architecture and in art because it was found to be a pleasing relationship. That may be true, but I think that it's totally irrational! |
|
The Heliocentric Theory by Copernicus In 1514, Copernicus wrote about the idea that the Sun was the centre of the solar system, but it wasn't until 1543, just before his death, that the theory was published. |

e by Bernoulli and Euler Bernoulli first produced an integral related to e, but it was Euler who in 1748, produced the equation that bears his name. |

i - Use your Imagination! What's more "irrational" than irrational numbers? The square root of -1 seems that way. It's an "imaginary" number, and the source of complex numbers. Imaginary, complex, what more could you ask? |
Pi and e - doublely irrational! What's more irrational than Pi? Pi and e together, two famously irrational numbers. |
