# Advanced Math/Analog Clock Design - Anticlockwise motion.

Question

Analog Clock Design
Dear Prof Scott

http://en.wikipedia.org/wiki/Clock
http://en.wikipedia.org/wiki/24-hour_clock‎

The 12 hour Analog Clock design attached in the figure will also
work ?. The seconds dial will move in anticlockwise direction.

The clock time displayed in the image can be interpreted as
2 hours : 50 minutes.

Similarly 24 hour clock will have 0-23 dials. the 0-23 dials will be in respectively as attached in the figure.

If such clocks are designed and manufactured by clock manufacturers will it be accepted by the consumers ?.

Do the above design has any flaws ?. Counterclockwise motion will be not accepted by the consumers because clockwise design looks more perfect design among the two ?.

Thanks & Regards,
Prashant S Akerkar

I don't think most people will accept them.

For the counterclockwise clocks, many people have a difficult time reading things backwards.

For the 24 hour clocks, most people would have trouble determining what the hour was.  Even if all of the hours were put on the clock, it would take most people a lot of time to determine where exactly the hour hand was pointing.

Currently, clocks can be read from a distance.  If there were 24 hours put on one clock, trying to determine which hour was appropriate would require the clock to be viewed at a much closer range.

What I think is the way to go is to recognize that with the technology we have today, hands on clocks are no longer required.  It is much easier to read if a clock displays the time numerically.  There is also no chance at all of the clock ever being read in error.  I mean, the hour is almost always read correctly, but for the minute, people would not need to worry about a difference of one or two minutes, for it would say exactly what minute it was.

At many jobs around the world for many years, time has been done electronically.  It was done with punch cards, so perhaps someone could get leave early and get someone else to do their punch card, but now it is done electronically in many places with a bar code on their security badge.

As far as how long it took me to respond, the computer could keep track down to the millisecond, yet still only gives the response in minutes.

A question for you is at races, they use to have people with a stopwatch keep track, but now they can do it electronically.  Yet even so this is the way it is done, how many places actually do it that way?

As something of interest, on a certain game show where the spelling of words is guessed, they converted to showing the letters with a computer.  Due to the objection of most viewers, the show quickly found out that most viewers didn't like this.  To keep their ratings up, they went back to hiring someone to go around and touch the letters as they lit up.

As an odd thing to interject, how many people do you know that can rub their head and pat their tummy?  I'm one, but there are very few others.  Or how about tapping your fingers from thumb to pinky and back again?  Yeah, I'm someone that can do that.  In fact, I can even tap one hands fingers back and forth while tapping the other hand only one way.  There are other strange things I do, like memorize scripture.  At one point, I have memorized Genesis 1 (creation of the world), Exodus 20 (the ten commandments), Psalm 1 (good for those who do good and bad for those who do bad), Psalm 23 (the Lord is my Shepherd who takes care of me), Psalm 150 (rejoice), John 1 (genealogy of Christ from Adam to Joseph), Matthew 5-7 (sermon on the mount), each chapter in Ephesians (how to live), and hundreds of individual verse.

Then again, maybe I'm just straying off track again ...

#### 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.
