A. I had a senior seminar for the school of engineering when I was graduating in 1988. The speaker was trying to make a point about how technology has changed. He asked, "How many of you know how to use a slide rule?" One person in the entire auditorium raised his hand--me. Maybe I learned because slide rules were common in the house where I grew up. My dad was a physics teacher. Recently, I received a half-dozen slide rules from an estate. I told some engineer friends about them...they asked if they could have one. The slide rule is the classic "tool of the engineer" and has curiosity about it.

How is richter scale, Ph, chemistry asid, decibel's and a slide rule are similar and different?
Q. How is richter scale, Ph, chemistry asid, decibel's and a slide rule are similar and different? I have to write it one one of my projects and i dont know how to explain that question. DO YOU?
Asked by igor f - Mon Apr 30 18:12:05 2007 - - 2 Answers - 0 Comments

A. Similiar: All of those scales have very wide ranges. They increase exponentially as you go up the scale. For example, a magnitude 4 earthquake on the Richter scale is NOT twice as powerful as a magnitude 2 one, but rather, hundreds of times more powerful. The other scales work in a similar way. Differences: They measure different things. The pH scale measures hydrogen ion concentrations, decibels measure the magnitude of sound, etc.

A. When electronic calculators came on the scene about 35 years ago, the slide rule industry went into a steep decline. They may not even make them any more. My thinking is your best bet is Ebay or craigslist.

How many logarithmic scales are there on a slide rule ?
Q. How many logarithmic scales are there on a slide rule ?
Asked by Wendy A - Sun Jun 25 12:50:58 2006 - - 1 Answers - 0 Comments

A. The slide rule (often nicknamed a "slipstick") is a mechanical analog computer, consisting of at least two finely divided logarithmic scales (rules), most often a fixed outer pair and a movable inner one, with a sliding window called the cursor. Before the advent of the pocket calculator, it was the most commonly used calculation tool in science and engineering. The use of slide rules continued to grow through the 1950s and 1960s even as digital computing devices were being gradually introduced; but in the early 1970s the electronic scientific calculator made it largely obsolete and most suppliers exited the business. Despite their similar appearance, a slide rule serves a purpose different from that of a standard ruler: a ruler measures… [cont.]

How accurate is a 1960's slide rule?
Q. ... in terms of the number of significant digits would be great. What is 3.7 x 9.3 using one?
Asked by Math is what? - Mon Jun 30 22:46:21 2008 - - 5 Answers - 0 Comments

A. Depends on the slide rule. In general, two places for sure and a pretty good estimate of the third. I had a circular slide rule (this was in the very early 1970's) that was good to 4 significant figures for numbers less than about 3. On a slide rule you would find that 3.7 x 9.3 was about 34.4. The last digit would be a bit uncertain.

A. You have to respect your bf's wishes, it's his child. Personally I wouldn't want to be in this situation. You bf thinks he knows whats right for him, and you disagree, maybe you should consider how strong your relationship really is. You can't successfully raise your son with a partner raising his son 180 degrees differently. If there is no birth mom in the boys life, and you are the only mom he knows, plus you WANT the job. I think you should push for an adoption of him. If all that is in place, I think you should treat him like your son (No differently) that goes for everything, including discipline. However If he still has a bio mom, you need to let your bf Handel the discipline.

Is it poor driving practice to allow the steering wheel to slide in your hands as you "unturn" during a turn?
Q. I am a senior and, when I learned to drive, test points were deducted if I allowed the steering wheel to slide in my hands. My daughter's driving instructor told her that it is OK to do that. Have the rules changed over the years? Is it OK to let the wheel slide as long as you think you have adequate control while it happens?

Survey: Do you enforce the rule "up the stairs" and "down the slide" with your kids on the playground?
Q. I witnessed a boy going up a spiral slide and a girl had decided to come down at the same time. Needless to say the girl ended up at the bottom with the wrong way boy on her lap. No one was hurt but I was surprised when the mother of the "wrong way" boy got up and got on to the girl about how she shouldn't come come down the slide when her son might be coming up. The above question is a rule for our kids so I wonder who else has this rule?

Asked by JustAsking - Fri Jul 6 13:14:39 2007 - - 4 Answers - 0 Comments

A. Generally you don't want to have any slide up for more than 60 seconds. The goal of your visual aid is to add to your presentation, and if you keep them up longer than 60 seconds your prospects will get bored. Also, make sure that your slides are actual visual aids and not your notes or outline. In all cases it is better to remove the PP presentation all together rather than put your outline up. This will assist you in giving a more professional presentation. Also, remember the top 3 rules of presentations: Get their attention Keep their attention Have a call to action Also, if you give a feature, give the benefit that the feature offers, and if you give a benefit give the impact.

A. Put the divisor on top of the other number. The answer is at one end of the slide rule. (7 on top of 258) If you cannot read the 258 exactly on the slide rule, you estimate its position as closely as you can.
