When discussing the origin and diversity of life on earth, many scientists believe you must limit yourself to explanations that only invoke natural causes. Therefore science cannot invoke "intelligence" as a possible cause. But it's part of our reasoning to recognize the effects of ...
Theoretical physicist Albert Einstein is almost universally considered one of the greatest thinkers of modern times. Yet few really understand the ideas and applications of his theory of relativity and other important works. Perhaps fewer still realize how important his research ...
Einstein's theories are directly applied to these ominous entities lurking somewhere in the universe. Not only does this installment explore what black holes are and what kind of research on them is being done today, but it also delves into how Einstein's theories led to their discovery at ...
We learn about what went into the development of Einstein's theory of relativity, a new direction in science that forever changed the way we see the cosmos and all that's in it. Through careful explanation, the viewer learns how Einstein's theories shaped what we know today about the ...
Why do we put food into containers, and why are they all so different? The need to match the package to the product is explained and illustrated using a range of different foods. We visit several food production and packaging plants and see the care taken to ensure the products reach consumers ...
How do you design a meal that meets certain criteria? This program looks at the role recipes, ingredients, and utensils all play when it comes to preparing food. We follow step by step instructions to make a chocolate cake and demonstrate the correct use of cooking utensils, considering ...
