Imaging maths - Inside the Klein bottle

When I was still at school I came across a picture of a Klein bottle in a weekly journal. I shared my fascination with a friend who was a glassmaker specializing in physics equipment for schools. A few days later I was a proud owner of a physical Klein bottle, made of glass. What to do with such a bottle? To my delight, this primitive but interesting thermometer did indeed show signs of life during the day. 5215873104_1a714bda8b_z.jpg (JPEG Image, 640 × 427 pixels) Your Photos on a Diet! Animal Sleep. Most animals have a daily pattern of rest and activity.

Animal Sleep

Some animals are more active during the day (diurnal) and some are more active during the night (nocturnal). How much time do animals spend sleeping? Well, it depends on the animal: References: This table was adapted from four sources: Aserinsky, E., Eyelid condition at birth: relationship to adult mammalian sleep-waking patterns, In Rapid Eye Movement Sleep, edited by B.N.

Click and drag the arrow to change the direction of launch of the spaceship. Choose Jupiter's path distance (the shortest distance of the initial launch point from Jupiter's orbital path) and initial speed of the spaceship. RESET: puts Jupiter into ready position at far left START: Jupiter begins moving at its orbital speed SHOOT: launches the spaceship Zoom in or out to see the full orbit of the spaceship! You can also right-click on the movie and zoom in to get a better view of the objects.

Note: Jupiter moves through a distance equal to its diameter in about 3 hours. *** This flashlet demonstrates in a semiquantitative way how a properly directed spaceship can pick up energy from a moving planet. Jupiter Data : Chinese version Copyright © Michael Fowler 2004.

Manual Transmission Mechanism The mechanism also called as “stick shift” is used in cars to change gears mannually Constant Velocity Joint This mechanism is used in the front wheel drive cars Torpedo-Boat destroyer System This system is used to destroy fleet in naval military operations. Rotary Engine Also called as Wankel engine is a type of internal combustion engine has a unique design that converts pressure into rotating motion instead of reciprocating pistons.

Ground Zero II

With Google's Maps framework and a bit of Javascript, you can see the outcome. And it doesn't look good. Now with Nuclear Fallout, Wind and Pressure Just what you need to be safe in these turbulent times: enter the address of that boss, teacher, colleague or loved one; select a weapon and a damage map mode. By clicking repeatedly on "Fallout" you can change the wind direction at the moment of the explosion. Where's the older version? Copy and paste the following to mashup the Ground Zero II script into your own website or blog: A ZIP archive with the source code can be found here. Science Caveat The damage caused by a nuclear explosion is affected by a multitude of variables, and some of these require powerful super-computers to be simulated properly.

A Cartography of the Anthropocene

The Anthropocene. We’re already there. This is our time, our creation, our challenge. Officially, this epoch does not exist. Yet. Unofficially however, the term is used more frequently in the scientific literature and, more recently, in publications dedicated to the general public. So, might you ask, what is the Anthropocene? First, the etymology. The term was proposed in 2000 by Paul J. Technically, the Anthropocene is the most recent period of the Quaternary, succeding to the Holocene. The Pleistocene (2.588 Ma to 11.7 Ka) was a tumultuous era, during which more than eleven major glaciations occurred.
