I started experimenting, making models, talking to experts in the field, taking their feedback, and refining, and I kept on refining and refining for nights and weekends for over five years.

Then we'll actually start refining that message, deeper and deeper.

From there, what I did was I started refining this cool idea I had.

And you have refining and delivery of that crude oil as what we call petrol or gasoline.

And the reason that we do number 2, rather than, refining next day, is I like to procrastinate.

And then lately, people are very concerned about cooking oil, because thousands of people have been found refining cooking oil from restaurant slop.

In the next great epoch of life, which applies for most of life, the brain is actually refining its machinery as it masters a wide repertoire of skills and abilities.

From electronics...oil refining and automobiles... to delivery...and telecommunications, and even if you're a Korean who doesn't know the President's name, you would have definitely have come across the words ShinHwa.

Maybe it's entirely possible that you could design a hash function that you think is completely collision resistant but someone might come along, a year from now, amp amp come up with a more clever way of refining a collision.

Also, every time you buy gasoline in the United States, half of it is actually being refined along the coast, because the Gulf actually has about 50 percent of our refining capacity and a lot of our marine terminals as well.

His specialty was actually refining and confirming other people's results, and this might sound like a bit of an also ran, but in fact, this is the soul of science, because there is no such thing as a fact that cannot be independently corroborated.

In a theory you repeat the process of refining the hypothesis through prediction, experiment, observation or creating new hypothesis again going through the circle again and again and again until your hypothesis becomes a theory that is a predictive and comprehensive description of some aspect of reality.

If the observation, however, is not in line with your prediction, then the hypothesis is rejected, and if the hypothesis is rejected, you need to come up with a new hypothesis, and this cycle going along from hypothesis through prediction through experiment through observation and gradually refining the hypothesis or coming up with alternatives.

And during that time, they're doing everything from going out and doing ethnographic research and doing the need finding, coming back into the studio, doing the brainstorming and design visualization to come up with concepts that might work, and then moving into the shop and actually testing them, building them, prototyping them, figuring out if they are going to work and refining that.
