Talks Christopher deCharms looks inside the brain

Neuroscientist and inventor Christopher deCharms demonstrates a new way to use fMRI to show brain activity -- thoughts, emotions, pain -- while it is happening. In other words, you can actually see how you feel.

Talks Henry Markram builds a brain in a supercomputer

Henry Markram says the mysteries of the mind can be solved -- soon. Mental illness, memory, perception: they're made of neurons and electric signals, and he plans to find them with a supercomputer that models all the brain's 100,000,000,000,000 synapses.

12 Tips to Learn How to Be Curious

Wikipedia defines curiosity as:

“any natural inquisitive behavior, evident by observation in many animal species, and is the emotional aspect of living beings that engenders exploration, investigation, and learning.”

Some people are born curious like Leonardo da Vinci. For others, curiosity just “kicked in” over time. Like anything else, curiosity can be learned. It’s never too late to learn how be curious. Finding your passion in work gets easier and the journey more interesting if you develop curiosity. So how can you learn it?

... so? how can you become curious? ... easy:

1. Don’t accept Spin: often what we’re exposed to is only the tip of the iceberg. Scratch the surface by digging a little deeper. Look at it from another perspective, then investigate any or all new information that you find.

2. Ask Questions: just like a little kid, think about “how?” or “why.” Asking more questions is like turning over more rocks. You never know what you’ll find.

3. Ask ‘What if…’: Think in the three possible scenarios: default to worst, most likely, and best-case scenario. Or think in terms of Sci-Fi like “what if, in a parallel universe” or “what if, in another life time, it had turned out like this?” Try the “what if…” approach.

4. ‘Turn Questions into Quests’: The first thing I could do when I get curious about something is go to or and do a search. There is always an answer to a question. Look for it!

5. Dig deeper than the RSS feed: breadth is nice, but depth is better. Taking a deep dive into the object of your curiosity is more satisfying than only looking at the high-level or macro view. Think verticals, not horizontals, unless your 360 view has you motivated to research breadth and depth.

6. Use available Tools: is a great resource for finding the books for your research. If you’re brainstorming, then mindmapping is always effective. Use note cards or all the usual ways you collect information so you can easily organize your thoughts later.

7. Put disconnected ideas together: over time, you learn how to see disparate things, realizing that they may be related.

8. Play: Find a way of incorporating what you like to do for play?

9. Get Proactive: it’s easy to accept things as they are, but we have take initiative if we want to be curious. When we’re learning how to be curious, you’re actually going out of your way to do it so it becomes a habit.

10. Network: talk or e-mail other who you respect on the thing you’re curious about.

11. Find a ‘Curiosity Buddy’: it’s more fun when we get curious with a buddy. It will make for lively discussions and more field trips to the bookstore!

12. Slow Down: Just sit. Reflect. Once you find great information, then sit down. Do nothing. Let the thoughts come to you, and then reflect on it.

Science's 10 Most Beautiful Physics Experiments

1. Double-slit electron diffraction

The French physicist Louis de Broglie proposed in 1924 that electrons and other discrete bits of matter, which until then had been conceived only as material particles, also have wave properties such as wavelength and frequency. read more

2. Galileo's experiment on falling objects

In the late 1500's, everyone knew that heavy objects fall faster than lighter ones. After all, Aristotle had said so. That an ancient Greek scholar still held such sway was a sign of how far science had declined during the dark ages. read more

3. Millikan's oil-drop experiment

Oil-drop experiment was the first direct and compelling measurement of the electric charge of a single electron. It was performed originally in 1909 by the American physicist Robert A. Millikan. read more

4. Newton's decomposition of sunlight with a prism

Isaac Newton was born the year Galileo died. He graduated from Trinity College, Cambridge, in 1665, then holed up at home for a couple of years waiting out the plague. He had no trouble keeping himself occupied. read more

5. Young's light-interference experiment

Newton wasn't always right. Through various arguments, he had moved the scientific mainstream toward the conviction that light consists exclusively of particles rather than waves. In 1803, Thomas Young, an English physician and physicist, put the idea to a test. read more

6. Cavendish's torsion-bar experiment

The experiment was performed in 1797–98 by the English scientist Henry Cavendish. read more

7. Eratosthenes' measurement of the Earth's circumference

At Syene (now Aswan), some 800 km (500 miles) southeast of Alexandria in Egypt, the Sun's rays fall vertically at noon at the summer solstice. Eratosthenes, who was born in c. 276 BC, noted that at Alexandria, at the same date and time, sunlight fell at an angle of about 7° from the vertical. read more

8. Galileo's experiments with rolling balls down inclined planes

Galileo continued to refine his ideas about objects in motion. He took a board 12 cubits long and half a cubit wide (about 20 feet by 10 inches) and cut a groove, as straight and smooth as possible, down the center. read more

9. Rutherford's discovery of the nucleus

When Ernest Rutherford was experimenting with radioactivity at the University of Manchester in 1911, atoms were generally believed to consist of large mushy blobs of positive electrical charge with electrons embedded inside — the "plum pudding" model. read more

10. Foucault's pendulum

Last year when scientists mounted a pendulum above the South Pole and watched it swing, they were replicating a celebrated demonstration performed in Paris in 1851. read more

"The world can change in an instant. So can the way you choose to see it. Why not choose to see the good in yourself and others." Bob Perks

We can choose how to see ourselves or others, this is completely true. See the world and people as being good and nice, peaceful and happy and you will find out that you are right regarding your vision about life. It is not a pure luck if you find good people in your life or a misfortune if you only encounter those bad ones. It’s up to you ... what do you choose to look for?

You find happiness because you are looking for it.

You find violence because you constantly choose to look for it.

Since I become aware of this fact, I decided what to look for in my life. I always choose, and in 90% of the time I receive what I am looking for. In the 10% it just came into my life and in that instant I decide if I want to give attention to it or I just refuse to give attention to what I don´t want to see, hear or experience. It´s what you choose that makes the difference, not what it comes.

I constantly refuse to watch bad news, I refuse to read negative things that happen in the world, and the best is that I always try my best in giving attention to only those things that matters to me.

People around me find me complicated and not understandable but I can understand why, if I look at their life and the results they attract in their own life.

It is no wonder that there are such horrible things happening in the world. We give attention to it and therefore we receive more of it.

We complain about the constantly bad news we see on TV, about the stupidity that is being shown on each new TV show, but we refuse to understand that we will always receive more from that thing that we are looking for. Start searching for the good news and you will receive it. Look for the good things that happen in this world, search for those people who know how to make a positive difference in this world and you will find them.

Have you ever wonder how many people have done something admirable today? Have you ever wonder how many people may have a successful story to share with you that may inspire you in the same time? Have you ever wonder how many people in this world helped somebody; did something good for somebody – just in this second? If not, is because you only choose to hear about the bad things that happen. If yes, than congratulation! I may ask you to read forward because you have something to share with us :)

Turn on the TV and you will see it, open you computer and see the first page of your bookmarked newspaper, and so on. What kind of movie have you seen lately, what kind of book have you read or what kind of story have you told to somebody lately? Is the kind of news that may inspire you or others, or maybe the one that can be projected as experience into your life? If not, choose again!

Good things, bad things, good people, bad people, good experiences, bad experiences; all this are connected. Try to search and give attention to what you want to see reflected in your experience, in your life, and you will receive more of it.

Have you done something good lately? Share your experience with us, and let others get inspired from your nice story. Write a comment about something that can inspire the readers of this blog. Let´s see how many good stories can be heard and shared. Let’s inspire others. Doesn´t matter in what language you will write, your story will inspire today somebody. I will post your story on my blog, together with your name (if you want) and a link to some other good news you want to share.

My story for today was to write this article, that I really hope, it will inspire at least one person that read it. And to get courage into writing 2 rows for us, watch this movie: Make a Difference. Good luck!!!!

I look forward for your story.

With love, Ella

stiati ca..?, stiai ca..?

Stiati ca ...

Cel mai inalt munte din Sistemul Solar se gaseste pe Marte? Se numeste Olympus Mons si atinge o inaltime de peste 24 Km.

Stiati ca ...

Planetele se invartesc in jurul Soarelui si in jurul axei proprii in sensul acelor ceasornicului. Venus este planeta care se invarteste in jurul axei proprii contrar acelor ceasornicului. Pe Venus Soarele rasare la vest si apune la est.

Stiati ca ...

Daca ai calatori cu viteza luminii de la un capat la altul al galaxiei Calea Lactee, ti-ar trebui 100.000 ani ca sa termini calatoria.

Stiati ca ...

Galaxiile calatoresc in spatiu si cateodata se ciocnesc, galaxiile mai mici disparand si fiind "mancate" de cele mai mari. Galaxia din Andromeda se indreapta spre galaxia noastra, Calea Lactee.

Stiati ca ...

Cea mai apropiata stea de Pamant este Proxima Centauri aflata la 4,23 de ani-lumina, adica 25 de milioane de milioane de km distanta de Soare. Asta inseamna, ca daca am avea o nava spatiala care ar calatori cu 50.000 de km pe ora, ne-ar trebui 88.000 de ani ca sa ajungem la ea.

Stiati ca ...

Sistemul nostru solar se afla in galaxia Calea Lactee, pe unul dintre bratele sale spirale, la 30.000 ani lumina departare de centrul ei, diametrul total fiind de aproximativ 100.000 ani lumina! Galaxia noastra impreuna cu alte 20 de galaxii se afla intr-un grup local (cluster) de galaxii a carei dimensiune este de circa 4 milioane de ani lumina. Acest cluster se afla la periferia unui supercluster de galaxii care are diamentrul 150 milioane de ani lumina. In centrul acestui supercluster se afla Virgo: un urias cluster format din cateva mii de galaxii. Acest supercluster se afla in mijlocul universului vizibil.... Deci limitele universului perceptibil se afla de jur imprejurul nostru la 20 miliarde ani lumina.

Stiati ca ...

in anii 1609-1610, Galilei face primele observatii astronomice cu luneta asupra petelor solare si descopera cei patru sateliti principali ai lui Jupiter

Stiati ca ...

Pluto era zeul care facea regulile in lumea mortii. Este un nume potrivit pentru cea mai intunecata, rece si departata planeta din sistemul nostru solar. In mitologia greaca este zeul Hades. Luna lui Pluto, Charon, are legatura tot cu lumea mortii. Charon este numele luntrasului care trece pe cei morti peste raul Styx, raul care delimiteaza lumea celor vii de lumea celor morti.

Stiati ca ...

Venus este considerata sora geamana a Pamantului pentru ca amandoua au cam aceeasi marime, densitate si volum.

Stiati ca ...

Pentru ca Mercur se invarte atat de repede in jurul Soarelui, romanii l-au numit dupa zeul mesager. El era curier in ceruri, zeu al negotului, hotiei, al calatorilor pe mare si pe uscat. In mitologia greaca, Mercur este similar cu Hermes.

1. A murderer is condemned to death. He has to choose between three rooms. The first is full of raging fires, the second is full of assassins with loaded guns, and the third is full of lions that haven't eaten in 3 years. Which room is safest for him?

2. A woman shoots her husband. Then she holds him under water for over 5 minutes. Finally, she hangs him. But 5 minutes later they both go out and enjoy a wonderful dinner together. How can this be?

3. What is black when you buy it, red when you use it, and grey when you throw it away?

4. Can you name three consecutive days without using the words Wednesday, Friday, or Sunday?

5. This is an unusual paragraph. I'm curious as to just how quickly you can find out what is so unusual about it. It looks so ordinary and plain that you would think nothing was wrong with it. In fact, nothing is wrong with it! But it is highly unusual, though. Study it and think about it, but you still may not find anything odd. But if you work at it a bit, you might find out. Try to do so without any coaching!



1. The third room. Lions that haven't eaten in three years are dead. That one was easy, right?
2. The woman was a photographer. She shot a picture of her husband, developed it, and hung it up to dry.
