A Brief History of Pi (π) - Exploratorium
Here’s a brief history of finding π. The ancient Babylonians calculated the area of a circle by taking 3 times the square of its radius, which gave a value of pi = 3. One Babylonian tablet (ca. 1900–1680 BC) indicates a value of 3.125 for π, which is a closer approximation. The Rhind Papyrus (ca.1650 BC) gives us insight into the ...
Your Weight on Other Worlds | Exploratorium
Scales measure the force of attraction between you and the Earth. This force of attraction between you and the Earth (or any other planet) is called your weight. If you are in a spaceship far between the stars and you put a scale underneath you, the scale would read zero. Your weight is zero. You are weightless.
Anatomy of an Egg - Exploratorium
Bumpy and grainy in texture, an eggshell is covered with as many as 17,000 tiny pores. Eggshell is made almost entirely of calcium carbonate (CaCO 3 ) crystals. It is a semipermeable membrane, which means that air and moisture can pass through its pores. The shell also has a thin outermost coating called the bloom or cuticle that helps keep out ...
Origins: CERN: Ideas: The Big Bang - Exploratorium
The universe began, scientists believe, with every speck of its energy jammed into a very tiny point. This extremely dense point exploded with unimaginable force, creating matter and propelling it outward to make the billions of galaxies of our vast universe. Astrophysicists dubbed this titanic explosion the Big Bang.
Visit the Exploratorium at Pier 15
The Exploratorium is more than a museum—it’s a gateway to exploring science, art, and human perception with every visit. Let your curiosity roam through more than 700 interactive exhibits in six spacious indoor and outdoor galleries.
Your Age on Other Worlds | Exploratorium
To Do and Notice. Fill in your birthdate below in the space indicated. (Note you must enter the year as a 4-digit number!) Click on the "Calculate" button. Notice that your age on other worlds will automatically fill in. Notice that Your age is different on the different worlds. Notice that your age in "days" varies wildly.
Build a Solar System Model | Exploratorium
If you build your solar system on a roll of toilet paper, you can make the Sun about .4 inches (10 mm) across and still fit the entire solar system on the roll. A standard roll of toilet paper has about 450 sheets that are about 4.375 inches long, hence the roll is about 164 feet long. You should check your toilet paper for length.
Flower Dissection: Plant Biology Science Activity | Exploratorium ...
Draw what you see, if it helps you. Carefully remove the petals from the flower (you can use scissors or gently pull the petals off). You will probably notice that the center of the flower contains long filaments (click to enlarge the photo below). Use the hand lens and/or dissecting microscope to examine the filaments.
Science of Eggs: Egg Science | Exploratorium
Egg proteins change when you heat them, beat them, or mix them with other ingredients. Understanding these changes can help you understand the roles that eggs play in cooking. Proteins are made of long chains of amino acids. The proteins in an egg white are globular proteins, which means that the long protein molecule is twisted and folded and curled up into a …
