As the boulder starts to roll down the hill, the potential energy it had at the top is gradually converted into kinetic energy. When we talk about kinetic energy, we usually mean the energy something has because it is moving. Anything that has mass (contains some matter that takes up a v...
Physics can, at base, be defined as the science of matter, motion, and energy. Its laws are typically expressed with economy and precision in the language of mathematics. Both experiment, the observation of phenomena under conditions that are controlled as precisely as possible, and theory, the...

Environmental scientists analyze a wide variety of environmental problems and potential solutions, includingalternative energysystems,pollution control, andnatural resource management, and may be employed by government, industry, universities, or ...
In the idealized version of how science is done, facts about the world are waiting to be observed and collected by objective researchers who use the scientific method to carry out their work. But in the everyday practice of science, discovery frequently follows an ambiguous and complicated route...
In making its case No Immediate Danger offers a barrage of facts: facts about fossil fuels; facts about energy consumption; many, many facts about fallout from the Fukushima nuclear accident, the main focus of Danger; paragraphs and tables and glossaries and appendices full of facts. Counterpose...

From bears to birds,from butterflies/'bAtaflarz/ to seahorses, animals make our planet lovely and interesting.And what's more, the Earth provides/pra'vaidz/ us with all the things we need, such as food, water, air and energy. It is our home and the only planet we know that supports...
the hearts of stars, in which two light atomic nuclei merge into a single heavier nucleus. Fusion produces very little nuclear waste, and no greenhouse gas emissions, which means it has long been touted as a potential clean alternative to conventional energy sources. But what drives this ...
This would allow us to just be and not put so much energy into our ego and thinking we are more right than others because we are educated in the study of scientific observation. Realizing that at any point in time the things you take for granted as fact could change in a split second...
