How do you know you exist? - James Zucker | TED-Ed René Descartes believed that most of what he acquired and learned came from the senses, but his senses had deceived him in the past. Can you give an example of when your senses have deceived you? Is there an experience that has made you doubt what you have seen or heard? Could this give you reason to doubt EVERYTHING you have learned from your senses? Descartes believed that if you doubt your own existence, you must exist to doubt it! René Descartes was an extremely talented man. Some famous quotes from Descartes are written below. “If you would be a real seeker after truth, it is necessary that at least once in your life you doubt, as far as possible, all things.” “Let whoever can do so deceive me, he will never bring it about that I am nothing, so long as I continue to think I am something."
Four questions that encourage growth mindset among students | Teacher Network Teachers have long battled with how to get their students to become more resilient and improve their mindset. One popular theory, pioneered by Carol Dweck, professor of psychology at Stanford University, is the idea of growth mindset. Dweck explains that some students believe ability is malleable and can be improved (a growth mindset), while others think it is set in stone, probably decided at birth (a fixed mindset). Evidence suggests that those with a growth mindset seek out feedback on how to get better, persist with work for longer and cope better with change – all attitudes teachers want to develop in their young charges. How can teachers encourage a growth mindset? When working with young people, choosing which behaviours to praise can have a profound impact. As well as thinking of the feedback you offer your class, there are certain questions you can ask to get them thinking about their own mindset: Is the effort today worth the reward tomorrow? This can be a simple weekend project.

The 2,400-year search for the atom - Theresa Doud Ernest Rutherford Although Ernest Rutherford is well known for his discovery of the nucleus, he did a lot of other research and experiments into topics other than the atom. He started his career studying electricity and magnetism and it wasn’t until he left his home of New Zealand and moved to Cambridge, England that he started working with the atom. Working under J.J. In 1911 after returning to England, Rutherford conducted his most famous experiment with alpha particles and gold foil which lead to his discovery of the nucleus. Where are the Electrons? After Rutherford discovered the nucleus, Neils Bohr (another of J.J. When Schrodinger’s equation is solved it does not give the exact location of an electron around a nucleus but as Max Born (yet another student of Thomson) discovered, it gives a probability density or area where the electron might be found. Schrodinger later went on to come up with a thought experiment or paradox that is referred to as Schrodinger’s Cat.

Just How Small Is an Atom? - Jonathan Bergmann Whether we’re zooming in to the wavelength of a gamma ray or zooming out to the size of a galaxy, it can be difficult to wrap our heads around the big numbers we’re measuring—like nanometers (10-9meters) or gigameters (109). Take a look at these efforts to represent big numbers. What are the strengths of each? How would you represent a large number (like a gigameter)? Marie Curie on Curiosity, Wonder, and the Spirit of Adventure in Science by Maria Popova A short manifesto for the vitalizing power of discovery. “Few persons contributed more to the general welfare of mankind and to the advancement of science than the modest, self-effacing woman whom the world knew as Mme. Among the ample anecdotes of the great scientist’s life and the many direct quotations of her humbly stated yet fiercely upheld convictions is one particularly poignant passage that speaks to the immutable resonance between science and wonder, the inextinguishable causal relationship between childhood’s innate curiosity and humanity’s greatest feats of discovery. I am among those who think that science has great beauty. Complement with this excellent 1964 meditation on what children can teach us about risk, failure, and discovery, then revisit artist Lauren Redniss’s sublime illustrated cyanotype biography of Curie, one of the best art books of 2011.

6 Tips for Building Soil for Your Raised Garden Beds and Planters When my wife and I first started gardening in earnest, the results were discouraging. The seeds we planted would sprout and begin to grow, but soon the rate of growth would slow and produce undersize vegetables. Some would succumb to damage from insect pests and slugs, and even when we purchased healthy seedlings for transplanting, they failed to grow to the size we expected. During our first few seasons of gardening we spent more time weeding than anything else. Over time we learned what most successful gardeners know: building soil is what gardening is all about. With hopes of sparing you the mistakes we made, here are some tips for building productive soil for your garden beds and planters. 1. We purchased a half-dumptruck load of soil to develop a perennial bed for blueberries. 2. It is common that new gardens do well in the first year, even without additional soil inputs. After one or two crops have been grown in a garden bed, we plant a ‘green manure’ cover crop. 3. 4. 5. 6.
Something surprising happens to your body when you freedive Featured image: Photo of freediver Hanli Prinsloo by Annelie Pompe. In 1949, a stocky Italian air force lieutenant named Raimondo Bucher decided to try a potentially deadly stunt off the coast of Capri, Italy. Bucher would sail out to the center of the lake, take a breath and hold it, and free-dive down one hundred feet to the bottom. Waiting there would be a man in a diving suit. Scientists warned Bucher that, according to Boyle’s law, the dive would kill him. Boyle’s law, which science had taken as gospel for three centuries, appeared to fall apart underwater. Bucher’s dive resonated with a long line of experiments — most of them very cruel and even monstrous by modern standards — that seemed to indicate that water might have life-lengthening effect on humans and other animals. He started the experiment by leading volunteers into an enormous water tank and monitoring their heart rates as they dove down to the bottom of the tank. This discovery was as important as it was surprising.
Failure - An Essential Ingredient For Coaching Success — Evercoach I am not sure why, but failure gets a bad reputation. If you study the lives of individuals who are highly successful, failure is almost always the stepping-stone to their success. In fact, without that failure, these highly successful people might not have been able to understand, achieve, or maintain their success. Failure is not celebrated in our society. We focus on the one who succeeds and wins, not the one who fails, even if he or she eventually wins. But, inevitably, failure is a key factor in everyone’s success. Statistics bear this out. Edison realized that it did not matter how many tries it took him to invent the light bulb. Michael Jordan, one of the most iconic players in the history of basketball, is often noted for his successes, his comebacks, and his game winning shots. Michael missed over 9,000 shots during this career. How Does Failure Relate to Coaching Success? When people first start coaching, they are ready to help others change their lives.

30 things you should never compost or recycle Remember the good ol' days — back when we only had one bin for trash? In retrospect, those days were actually more wasteful than good. We sent things to the landfill that might have nourished our yards, and buried them side-by-side with materials that should have been reclaimed and put back in the production chain. Today, most of us have two bins: one for compost and another for recycling. We've rounded up 30 things people mistakenly try to compost or recycle. Bread products: This includes cakes, pasta and most baked goods. Cooking oil: Smells like food to animal and insect visitors. Diseased plants: Trash them, instead. Heavily coated or printed paper: This is a long list, including magazines, catalogs, printed cards and most printed or metallic wrapping paper. Human or animal feces: Too much of a health risk. Meat products: This includes bones, blood, fish and animal fats. Milk products: Refrain from composting milk, cheese, yogurt and cream. Sawdust: So tempting.
The Mistaken Assumptions That Changed Physics History - The Nature of Reality “Don’t assume,” they always say. Last month, Avi Loeb, an astrophysicist at Harvard, published an essay on how mistaken assumptions have delayed the progress of astronomy. In the same spirit, I wanted to find out how the course of physics has been influenced by assumptions, acknowledged or otherwise. Can lessons from the past help us be more aware of the assumptions we bring to physics today? Is it desirable—or even possible—to work without assumptions? In the years after scientists came to accept light as a wave, brilliant researchers spent untold hours chasing after the “ether,” hypothetical stuff through which light waves were thought to propagate. If Einstein resolved one roadblock, he set up another. Dice or no dice? It’s hard to imagine an astronomer dismissing observational data on the evidence of her “instinct for astronomy,” which highlights a key difference between the two fields. Hidden assumptions can also live at the heart of how we do science.
Treat Failure Like a Scientist I recently had a wonderful conversation with my friend, Beck Tench. During our chat, Beck told me about an interesting shift in thinking that occurred while she worked at a science museum. During her time there, Beck said that she learned how to treat failure like a scientist. How does a scientist treat failure? And what can we learn from their approach? Here’s what Beck taught me… Treat Failure Like a Scientist When a scientist runs an experiment, there are all sorts of results that could happen. And that’s exactly how a scientist treats failure: as another data point. This is much different than how society often talks about failure. Failing a test means you’re not smart enough. But for the scientist, a negative result is not an indication that they are a bad scientist. Your failures are simply data points that can help lead you to the right answer. Failure is the Cost You Pay to be Right None of this is to say that you should seek to make mistakes or that failing is fun.
