Question
Dear Prof Scott

The flour mill machine Takes wheat as the source raw material and the process converts giving us Flour as output.

Is it possible to reverse the process by designing a machine which will give us wheat from flour?.

Thanks
Prashant

Answer
As can be seen in http://www.madehow.com/Volume-3/Flour.html ,
the wheat needs to be ground up to make flour.

As can be seen, the wheat (or any other vegetable) must be ground up so that the wheat can be extracted.

After reading the article, I see there are 16 steps required to make wheat into flour.

Perhaps steps 1, 2, 4, 5, 6, and 16 could be reversed, but the steps numbered
3, 7, 8, 9, 10, 11, 12, 13, 14, and 15 would be impossible to reverse.

From this it can be concluded to reverse the entire process would be impossible.

Have you ever seen a movie called, "Princess Bride"?
A word used throughout the movie is "inconceivable".
To reverse flour would be even harder than that.

To undo flour would be like to un-cook food, putting paint back in the jars after it was put on the canvas,putting back together food after it was eaten, making a car be like new (though some shady car dealers claim it has been done), undoing the process that makes oil into gas, un-burning a piece of paper, restoring a burnt down house or any of another number of things.  There's no way it do it by human hands or by using anything that we have created.  There are some cases where a good imitation can be made, but not an exact replica of the original.

Now as it says in Matthew 19:26, "And looking at them Jesus said to them, 'With people this
is impossible, but with God all things are possible.' "  I've seen many miraculous healings,
but have never seen any of the things mentioned in the last paragraph be done.

Scott A Wilson

Expertise

I can answer any question in general math, arithetic, discret math, algebra, box problems, geometry, filling a tank with water, trigonometry, pre-calculus, linear algebra, complex mathematics, probability, statistics, and most of anything else that relates to math. I can also say that I broke 5 minutes for a mile, which is over 12 mph, but is that relevant?

Experience

Experience in the area; I have tutored people in the above areas of mathematics for over two years in AllExperts.com. I have tutored people here and there in mathematics since before I received a BS degree back in 1984. In just two more years, I received an MS degree as well, but more on that later. I tutored at OSU in the math center for all six years I was there. Most students offering assistance were juniors, seniors, or graduate students. I was allowed to tutor as a freshman. I tutored at Mathnasium for well over a year. I worked at The Boeing Company for over 5 years. I received an MS degreee in Mathematics from Oregon State Univeristy. The classes I took were over 100 hours of upper division credits in mathematical courses such as calculus, statistics, probabilty, linear algrebra, powers, linear regression, matrices, and more. I graduated with honors in both my BS and MS degrees. Past/Present Clients: College Students at Oregon State University, various math people since college, over 7,500 people on the PC from the US and rest the world.

Publications
My master's paper was published in the OSU journal. The subject of it was Numerical Analysis used in shock waves and rarefaction fans. It dealt with discontinuities that arose over time. They were solved using the Leap Frog method. That method was used and improvements of it were shown. The improvements were by Enquist-Osher, Godunov, and Lax-Wendroff.

Education/Credentials
Master of Science at OSU with high honors in mathematics. Bachelor of Science at OSU with high honors in mathematical sciences. This degree involved mathematics, statistics, and computer science. I also took sophmore level physics and chemistry while I was attending college. On the side I took raquetball, but that's still not relevant.

Awards and Honors
I earned high honors in both my BS degree and MS degree from Oregon State. I was in near the top in most of my classes. In several classes in mathematics, I was first. In a class of over 100 students, I was always one of the first ones to complete the test. I graduated with well over 50 credits in upper division mathematics.

Past/Present Clients
My clients have been students at OSU, people who live nearby, friends with math questions, and several people every day on the PC. I would guess that you are probably going to be one more.
