I work as a software developer. I have a long term mission to develop strong AI that will pass the Turing Test. I am religious. I strongly believe that we should teach logic classes in public schools. I like to fiddle with Mathematics.

• Help with NPN Transistor Diagram?

I am learning about electronics. There is a diagram (Diagram 'B') at http://www.technologystudent.com/elec1/transis1.ht...

I understand how the transistor is turning on the LED. I get that you need the 1K resistor before the base of the transistor or it will fry the transistor. I don't get why there is a strait connection between the switch and the 0v (with the other 1K resistor between them). Why not have the only connection to the 0v be to the emitter of the transistor?

Also, I am having a hard time understanding how many ohms my resistors should be. Why did they pick the ones they did on that diagram?

• Write an equation for 1 + 11 + 111 + 1111 ...?

f(n) = 1 + 11 + 111 + 1111 + ... where n is the number of 1's in the last term.

Write an equation for f(n) that doesn't use Epsilon or a series of terms. in your answer.

• What is the best way to make a positive impact on the world?

Anytime I talk about societal problems, I try to think about possible solutions, and I always trace it back to the same thing.

If people in power had the opportunity, skills and power to make better decisions, then society would improve. It seems the way to do that is through targeted education. Teach manditory classes in high schools to teach people how to make informed, intelligent decisions. Besides a Decision Making class, I would also like to see manditory classes in Critical Thinking / Logic, Relationships, Parenting, Finance, Communications, and General Job Skills.

What is the best way I can influience high schools / middle schools to teach these classes, or is there a better way to make a positive impact on the world?

• What is a meritocracy and how does it differ from a democracy?

What is a meritocracy? Is there any current examples of a working meritocracy in the world? Is the current government better or worse than a meritocracy and why?

• How to build a DVD library?

I have purchased approximately 150 DVDs that are on a shelf that is now full. I've setup a computer with Vista's media center edition software attached to a projector. I'd really like to rip the DVDs to a large network drive and then I can put my DVDs in a box somewhere so they don't take up so much space. I want software that will rip the DVD into a format that I won't lose video or surround sound quality, and is super easy to access through media center, ideally from video library from the menu. I'd also like to do the same thing with my Blu-Ray disc in the future. What software should I buy? How does it work?

• Double slit experiment. Why?

In the double slit experiment, what really boggles my mind is that when both slits are open, there is an area of the screen where electrons rarely hit, which happens to correspond to the area where the wave function would interfere, hence wave particle duality. Did the electron start out as a wave and become a particle? Why didn't the wave become a particle as soon as it passed the barrier with the slits? Someone please explain what is happening physically, not mathimatically? And please don't throw in particle consciousness, or alternate dimensions.

• Please show me the steps to solve this.?

Sorry. I left out some symbols

If 3x^2 – 2x + 7 = 0, then (x – 1/3)^2=

• How do you want to improve the world?

Here is my thought.

1. The problems in the world that people have control over, are caused because of people's actions or lack thereof.

2. Actions are determined by choices.

3. If we improve people's choices, the actions and outcome will improve.

4. There are at least two things that will improve choices, better thinking skills and better intended outcomes.

5. Improving thinking skills can be achieved by teaching critical thinking.

6. In order to teach critical thinking to everyone, it should be a mandatory class in High Schools.

So, I want to improve the world through making critical thinking classes mandatory in High Schools. I recognize that there is already an emphasis on teaching critical thinking in other subject, but I don't feel that it is enough. It should be it's own class.

To determine how much and what ways we should teach every class in schools, we should find a way to estimate the outcome of various methods and use it to find the proper balance.

I will query better intended outcomes in a different question.

• What is the best HD Projector for under \$2000?

I'm looking for something that will support 1080p. Good contrast (above 10000:1) and decent lumens (above 1200) are also important.

• Is it moral and ethical to start a large scale breading program?

The goal would be to improve the human race through selective breading. Subjects that were healthy, kind, intelligent, motivated and attractive would be paid large amounts of money to have many children. The children would be raised in a healthy family environment. What are some of the pros and cons to this approach?

• Do you think the world would be better if we had a regulated meritocratic government?

The problem with a democratic republic is that the general public don't make informed rational decisions, and the representatives care more about their own political interests than the short and long term interests of society.

• I think therefore I am?

Is this equivalent to "I think, therefore I exist?" Is this something we can know to be true? Why? Is there anything else we can know to be true? If no, what?, If yes, why?

• If are put in loose loose situation what would you do?

There are two ships each containing a large amount of explosives. A super villain is watching from a nearby tower and has placed a remote detonator on each ship which will blow up the other ship. It's 9:00 PM. If neither ship explodes by midnight or if anyone leaves either boat, the villain will use a remote detonator to blow up both ships.

You are on one of the ships. You can either blow up the other ship which will save the people on your own boat, or you can wait until midnight and both boats will be blown up. The sooner you blow up the other boat the less the they have to blow you up.

• Is there anything wrong with doing everything I do for my own benefit?

I'm still kind to people. I just do it because it makes me feel better. I also am religious and am trying to do things that would get me to heaven, because I believe I will be happier in heaven.

I’m religious and politically unaffiliated. What I’m trying to say isn’t about religion or politics.

I’m having trouble explaining to others what I’ve come to know. I want more people to think rationally. I feel like if they could only understand what I understand that things would get better. People aren’t taught to think rationally and very few people develop the ability on their own. Many of our leaders don’t understand how to make good decisions. Very few people are willing or able to question the way it’s always been done. People have the false idea that decisions are arbitrary. They are so locked into thinking the way their parents think or how culture thinks that they have lost any objectivity they once had. How long do we need to suffer? Is there anything meaningfully that I can do?
