Slingshot Instructions: (after you've read these, click here to get a bigger picture.) 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.

Calculadora en línea Simbólico y Solver Create a Killer Business Plan - Martha Stewart Community You've got the idea, now package it well! The way you present your company and vision will determine whether you get the right financial partners and the right deal. Marketing Your IdeaLife is marketing.

Predatory slime mould freezes prey in large groups – Not Exactly Rocket Science This post is part of a celebration of the 2-year anniversary of open-access journal PLoS ONE. Gathering in large numbers is usually a good way of protection yourself against predators, and it’s no surprise that mass defence is a common strategy in the natural world. But it doesn’t always work. There is one hunter that has found a way to use group defence to its advantage. It allows its prey to gather in large numbers and then freezes them in place with a chemical weapon, providing it with a bountiful banquet to eat at its leisure. D.caveatum is a member of the dictyostelids, a group that also goes by the names of “slime moulds” or “social amoebae”. The majority of dictyostelids, such as D.discoideum, are some of nature’s most vivid examples of cooperation. It’s a lovely story, but add D.caveatum into the mix and you get a very different ending. (Watch D.caveatum (the red arrows) devour D.discoideum (the green arrows).) Reference: Clement Nizak, Robert J. More on awesome predators:
Calculadora de Porcentajes A percentage is also a way to express the relation between two numbers as a fraction of 100. In other words, the percentage tells us how one number relates to another. If we know that number A is 25% of number B, we know that A to B is like 25 is to 100, or, after one more transformation, like 1 to 4, i.e., A is four times smaller than B. This is what the percentage calculator teaches; what is a percentage and how to find a percentage of two numbers. How to find a percentage of something? At first, let's start with the most straightforward example with 100 cookies. Let's go with something a bit harder and four times more delicious: 400 cookies!

Percentages are sometimes better at expressing various quantities than decimal fractions in chemistry or physics. A percentage is also a way to express the relation between two numbers as a fraction of 100.
The 5 Most Insulting Ways Products Are Advertised to Men It wasn't so long ago that pipe-smoking men in dark suits could sell their products to women with a patronizing pat on the head and a wink. Those days went the way of the cocktail lunch, but sexism still rages in the advertising world. It's just that now, everybody gets in on it. And just as ads in the 1950s assumed that all women were housewives desperate for new ways to starch their husbands' shirts, advertisers today demonstrate an extremely low opinion of their male customers. That's why there are so many ad campaigns that ... #5. Photos.com Most of us aren't old enough to remember back when women were seen as nothing more than baby-making servants with childlike brains, but if vintage advertisements are to be believed, we're lucky humanity didn't just devolve into a species of red-lipped cretins.

Why not turn the moon into a solar power plant? Have you looked at the moon lately? It's fascinating. And, if a certain Japanese construction firm has its way, it could also become the answer to Earth's burgeoning energy crisis. Look, I know it might sound like I made this one up, but it's true: The R&D group at Shimizu, one of Japan's largest construction firms, recently proposed building a belt of solar panels across the moon's equator. Shimizu describes the process in a series of steps: First, the solar cells closest to the sun will convert sunlight into electricity, and this power will be transported via cables to the side of the moon facing Earth. The end goal is to "supply energy to the entire world." Click here to check out Shimizu's construction plans. As you might (correctly) assume, there are numerous obstacles involved. Check out this video on the project and let us know what you think about turning the moon into a solar power plant.
