Random Thoughts 7

So my phone Android screen keeps making 180 turns despite disabling "Landscape" mode. Other possible culprits I can think are gyroscope or accelerators that have overly-sensitive responses. Or maybe some app permissions are overriding the landscape mode? Maaybe some devs like @DaveC426913 or @jack action , or anyone else can suggest a way of disabling the auto 180 flip? Annoying to watch a video, do anything in the phone and have it flip for no apparent reason.

Check you device's setting about Screen Rotation. Is turned on or is turned off?

Thanks, my phone doesn't have that option; "Landscape" is the closest to it.

Understandable, I guess. I had one just as bad. One might guess that you have a very cheap device.

Thing is there may be internal permissions at the app level, that may override the non-landscape option, or accelerometers, gyroscopes, etc. I think it goes beyond the landscape setting. Edit: based on my cursory research.

I've heard recommendations that one should walk at least 10,000 steps per day. Maybe my calculations are wrong, but at a brisk pace, say 4-5 miles/hr, for someone of average height: 5'9"-5'10"( re: length of step), that would take at least 3 hours . Who can devote that much time to walking on a work day?

Try performing a few measurements, rethink this, and recalculate. I really mean that. Fairly brief but precise activity, and a small mathematical practical adventure, which you may be interested in testing of the results.

I was being lazy , hoping someone would have already done them Edit. at some point. I found out the rule of thumb of 0.82 x height, giving us here 56.2" . Then, (10,000)(56.2")/12=562000/12=~47,000 feet. There are approx Edit: ( per Symbolipoint) 5,280 ft in a mile. 47,000/(5280)~8.9 miles. So that's the distance total . At 4.5 miles per hour, that's a little more than 2 hours. Still a considerable amount of time, though I doubt few will do it nonstop.

I walk slightly over 2000 steps per mile at 120 steps per minute. That's about 17 minutes per mile. Normal walking around is 1500 to 2000 steps per day, so a goal of 10,000 steps per day would require a walk of slightly over 4 miles, or slightly more than one hour.

Only a few years ago, my easy walk pace was 15 minutes per mile. Old age decrepitude is slowly winning.

Two questions so far.
Who is Edith?
Have you either remembered correctly OR looked for the value how many feet in one mile? (5280)

So I answered the unit conversion fact but you'll have to answer the other question.

But whatever, I only suggest trying some few precise steps to start your measurements. NOT going a full entire mile. Then use proportion to do the calculations.

Thank you. Edited and corrected.

I found out the rule of thumb of 0.82 x height, giving us here 56.2"

This is for a stride length. A step length is half of that:

Step Length vs. Stride Length​

The step length is the distance from the heel print of one foot to the heel print of the other foot during a walking stride. This is the distance traveled forward by a single leg. An average that you will see listed in many places is 2.2 feet (0.67 meters) for women and 2.5 feet (0.762 meters) for men, but it depends very much on height.1

Stride length can mean the same thing as step length, or it can mean the distance traveled by the heel of one foot to the next time that same foot strikes down. In other words, it is two steps since in that time the other foot has also touched down once.

If you set your pedometer for your step length and discover it seems to be halving your distance, read the instructions again. It may want the stride length, which is two steps. Also, in the reverse case, if you at first thought the pedometer needed the stride length but you seem to be getting double the distance, read again as it may have really wanted the step length.

From the same article, you also get the average step length by height (although they used the term "stride" to make it just more confusing):

Average Stride Length by Height​

When you use your height to determine your stride length, you get a rough estimate that isn't personalized. But if you're wondering how long your stride length should be, or the normal step length for your height, there is a way to measure and estimate. It can be useful to check your results by the other methods. It is the method used in the automatic settings of many pedometers and activity trackers:

• Females: Height in inches multiplied by 0.413 equals stride length
• Males: Height in inches multiplied by 0.415 equals stride length

But even knowing that, to answer your question:

[...] that would take at least 3 hours . Who can devote that much time to walking on a work day?

Answer: A postman.
