A poet once said, "The whole universe is in a glass of wine." We will probably never know in what sense he said that, for poets do not write to be understood. But it is true that if we look in glass of wine closely enough we see the entire universe There are the things of physics: the twisting liquid which evaporates depending on the wind and weather, the reflections in the glass, and our imagination adds the atoms. The glass is a distillation of the earth's rocks, and in its composition we see the secrets of the universe's age, and the evolution of the stars. What strange array of chemicals are in the wine? How did they come to be? There are the ferments, the enzymes, the substrates, and the products. There in wine is found the great generalization: all life is fermentation. Nobody can discover the chemistry of wine without discovering the cause of much disease. How vivid is the claret, pressing its existence into the consciousness that watches it!
If in our small minds, for some convenience, divide this glass of wine, this universe, into parts - physics, biology, geology, astronomy, psychology, and so on - remember that nature does not know it! So let us put it all back together, not forgetting ultimately what it is for. Let us give one more final pleasure: drink it and forget it all!

Do you remember having a cold in 5th grade? Or the flu a couple years ago? Your immune system does. Our bodies hold many levels of immune defense.Physical barriers like skin, the innate immune system, and our body’s most powerful defender, the adaptive immune system. Millions of B cells and T cells and antibodies are constantly on patrol for germs and antigen invaders. As scientists learn more about how this system works and how to engineer it, could we ever actually be immune to everything?

Our lizard friend the Gila monster probably has no idea that a chemical in its spit inspired one of the most important medical advancements of the 21st century. But this story is really about something bigger. Something deeper, beneath the surface. About why we do science in the first place. And about what kind of questions are the best ones for scientists to ask.

Why is some science fiction so good at predicting actual science?
Don’t miss our next video! SUBSCRIBE! ►► http://bit.ly/iotbs_sub
Do Ray Bradbury, Arthur C. Clarke, Jules Verne, Philip K. Dick, Hugo Gernsback, Robert Heinlein, or Isaac Asimov hold a candle to H.G. Wells when it comes to correctly predicting the future of science via science fiction?
And why does some science fiction do such a good job of predicting the future in the first place?
Check out these other great H.G. Wells-inspired videos from our PBS friends:

Check out the NEW Math Game we made at https://www.MageMath.com/
It is a full video game called Mage Math that helps kids build confidence in math while having tons of fun.
This fun math video teaches Division to kids and helps them understand the vocabulary used in division. Just like multiplication there are new words we use and we learn about them in this fun educational video that makes a great introduction or review to division.
Students in 2nd and 3rd grade learn about division so feel free to use this video in the classroom during math time. Fractions, factors, division, addition, subtraction and many more subjects are what we teach with our fun videos.
Please check out our games and other videos on our websites.
