African proverb: "If you want to go fast, go alone; but if you want to go far, go together." I am currently finding someone to start the journey, to make things happened in this world. If you agree, reach me.

- TED is the place where advance idea get presented
- Idea can wrong, what we believe are often proven wrong. Especially advance idea.
- What is the difference between advance idea and bad science?
Confusing hypothesis with fact
Didn't have solid background -> how can you check solid background
Report both side of the picture
Should reference to journalism
Checkable claims
inconvenient truth: austin was associated with vaccin, but turn out to be false. Can one really know that before it was proven false by the scientific community.
If not, we have to bear with us that there will be always a risk of false information on the information we provide.
- Bad letter, should have shown the usual routine that TED is doing instead, what is the background check they are doing.
No real case example are what is, what is not bad science
Rely solely on where the presenter works, studied, instead of what is true
I guess I just don't like the word "bad science"; science is either true or false; not good and bad.
Speech skills:
- As compared to Antonio Damasio, the speech is far more interesting. He asked questions that interesting and important, made the point easier to understand: "why computer can win chess, but is bad to move chess piece", and offer important insight.
Important question: - Why do we have brain?
-> Not because we have to think;
-> But because we have make complex movement
- The proof that brain is for movement:
Sea Squirts, the moment they settle down, they digest their neuro system.
- Computer (IBM DeepBlue) can beat human in chess, but might not be able to control movement to move things. (Defined goal that can be optimize vs. not defined, complex goal)
- What is the challenge of the brain: move many muscle, identify signal from noises.
- Bayesian System: Unifying system in statistic and machine learning (related post from Jasond Hsu)
Two source of information:
1. coming from current input (sensing) (red)
2. accumulated input from the past (yellow)
Need to decide the optimal ratio, so to make the best prediction
- Making prediction, so that you can know what senses are from the outside, so that we are not fool by ourself( can't tickle yourself)
0.1 ~ 0.2 sec
- Escalating of force (because prediction, the one that gives the force, feel less than actual)
70% of escalation
- Problem: simple task, huge amount of choice; but we seems to move the same way.
We understand the dots, we move the same way -> evolution.
We want to avoid negative consequences. Bigger forces -> bigger noises, we want to avoid bigger force.
Classic scholar talk, it's great that I am moving from the stimulating emotional TED talk to pure ( and boring ) intellectual talk.
1. Conscience; displaying image, sound, imagine and reflect. -> It's basically the same part where the brain feels.
2. Self:
What is self? Are we the only animal to have self? (Linkage to: other animal doesn't seem to understand mirror)
- Key problem about self: "How can you have this reference point, this stability, that is required to maintain the continuity of selves day after day?"
-> hypothesis: We generate brain maps of the body's interior and use them as the reference for all other maps.
-> the self is bind with our interior system, which also has to be very stable.
-> The idea so far, seems to be that self is generated from the frontal cortex, but though it is related, Damasio doesn't think it is because of the cortex, only that because the cortex allow the self to have a rich mind.
Google News -> search for content provider; display what the paper thinks is important Turn out to have too few news source.
HN -> a platform; where people discuss news; a great algorithm is used to display the most important ones Needs a better UI; customized to different area, people's interest
