# Time

Time
by Bob Day

Time is weird.  Maybe not as weird as consciousness, but definitely weird.  But there are some simple things we can observe about time.  First, it seems to be the property of our universe that provides the capacity for change. Without this capacity, things could not change.  We see a car moving.  "Now" it's at one spot.  A little bit "later" it has moved a little farther down the road.  Without time it couldn't do that — it would remain frozen in place.  Question: Does time always involve motion?  I think maybe it does.  Suppose we're listening to music.  The sound is changing.  The sound is a sensation in our heads, and apparently not moving.  But what causes the sound is atoms vibrating — moving back and forth — in the air.  So sound requires motion to make it.  I'm pretty sure it's all like that — same thing with a leaf changing colors: chemical reactions are involved, and, consequently, motion of atoms.  Maybe you can think of a counterexample — an example of some kind of change that doesn't involve the motion of something.

Here's another weird thing about time: It seems to go at the same rate for everything.  The definition of one second is this: "The second is the duration of 9,192,631,770 periods of the radiation corresponding to the transition between the two hyperfine levels of the ground state of the cesium 133 atom (at 0 degrees K)."  OK, we have a stopwatch and we'll clock our cesium 133 atom.  We time one second on our watch and count.  Sure enough — 9,192,631,770 periods!  Let's do it again.  We get the same thing, 9,192,631,770 periods.  So time went at the same rate in each of our measurements.  But wait — that's our definition of time: whenever the cesium 133 atom makes 9,192,631,770 transitions, that's one second, no matter how long it takes.  So our first measurement might have taken a second, and the second measurement, 100 years.  Except that, if that were the case, our stopwatch (and everything else) would have had to slow down too.  That's what I meant when I said that time, apparently, goes at the same rate for everything.  And if that rate changes, it changes for everything at once.

So, as far as we can measure, time seems to flow at the same rate for everything, at least in our neck of the universe.  But who is to say that time might not flow at a different rate in a chunk of space (in our same relativistic frame) a zillion or so light years away from us?  The immediate consequence of that might be that the speed of light in that chunk of space would be different from our speed of light.  Possible?  I couldn't say either way.  But, as far as I know, there is no rule that says the flow rate of time has to be a constant throughout the universe.

# Consciousness Totally Explained and Elucidated

Consciousness Totally Explained and Elucidated

Copyright (C) January, 2020 by Bob Day.

Like I have even a clue.  I don’t think anyone does.  But I do have some thoughts about it.  Here’s the definition I’m using: “Consciousness” — that mysterious phenomenon by virtue of which we can say “I” in our minds.

1. First off, you’ve gotta wonder why consciousness is even necessary — why it’s useful from the standpoint of evolution; that is, what survival benefit does it confer?  From a survival point of view, why wouldn’t we do equally well just receiving and reacting to stimuli in a totally automatic sort of way? — like we assume a computer does.  It could be a pretty complex path between the stimulus and the reaction — for example, a computer can play an excellent game of chess or the Chinese game of go, but it’s still completely automatic and “mindless”.  I have no clue on this point.  But “Nature” does seem to have gone to quite a bit of effort surrounding its implementation of consciousness — it’s given us an elaborate internal “display screen”, or in Microsoft Windows terminology, an internal “desktop”, that allows us to speak with ourselves internally, to see images in our minds, and to “think”.  So, obviously, there is an evolutionary benefit to incorporating consciousness into the design of creatures over a purely automatic, reactive design.  Or is there?  Anyway, my own suspicion is that consciousness is just an inexpensive  solution to an evolutionary problem.

2. Questions without answers (because we don’t know the answers, for certain):

Suppose we took a person’s brain out of their head, took the brain apart, cell by cell, neuron by neuron, put it back together again, and put it back into the person’s head.  Would the person have consciousness?  Would he or she be the same person with the original consciousness (whatever that might mean)?

Suppose we took a person’s brain apart and duplicated it cell for cell.  Then we put the duplicate brain back into the person’s head.  Would the person have consciousness?  Would he or she be the same person?

Suppose we put the original brain into one body and the duplicate brain into another?

Suppose we took a person’s brain apart, duplicated it cell for cell with semiconductor chips, and hooked up the semiconductor brain into the person’s body?

3. Suggestion for an experiment.  I thought about the idea of two people having duplicate brains a little bit more, and I can imagine one result being that they would share a consciousness. (Note – I’m got going so far as to say that this is a real possibility — that’s why I used the word ‘imagine’.)  Going a little further, maybe creatures get consciousness somewhat analogously to how a radio receives a radio signal.  Maybe we are all tuned to some kind of central source of consciousness.  Maybe each of us is tuned to a different “frequency” of that central source, with the result that each of us has a separate consciousness.  So maybe if two people have exactly duplicate brains, they are both tuned to the same “frequency”, and thus share a consciousness. (It’s my blog, so I can take these flights of fancy!)

There’s just a smidgeon of evidence that this is a possibility: Many sets of identical twins say that that they have a sense of one another.  One can sense when the other is in danger, can feel the other’s emotions, can “feel the other’s pain”.  Perhaps the brains of identical twins are tuned very close to the same “frequency”, so their consciousness overlaps to a degree.  As far as I know there is no good experimental evidence for this.  In fact, as of 2015, James Randi’s million dollar prize for reliably demonstrating any kind of paranormal phenomena had gone unclaimed for 19 years, and it was canceled that year.  The evidence, such as it is, is all anecdotal.  That doesn’t mean it’s worthless, but it does mean we’re not on solid ground.

My idea for an experiment is to nail down what I said in the previous paragraph, one way or the other.  Get some cloned pairs of mice that are as close to being exact duplicates as possible.  Then take one mouse of each pair, give it a little electric shock, and see whether there is any reaction from the other one in the pair.  Or, teach one mouse in each pair to run a maze, and then see whether the other mouse in the pair can learn the maze faster.  Of course, we have to have all the usual experimental controls: mice in each pair separated; a control group of mice, etc, etc.

Except.

A while ago, in a computer programming newsgroup on the Internet, there was a discussion about the same thing.  Some people in that discussion said they heard a voice; others said they didn't.  One guy said he sometimes heard a voice, but when he did, he "turned it off".

Well, go a whole lifetime and then learn something totally new about something very basic.  Not obvious at all.  Maybe people who hear a voice in their head as they read learned to read phonetically, and maybe people who don't learned via the sight method.  Maybe.  And there's this theory:  Maybe there are two different kinds of ability to read built into the circuitry of our brains, and maybe some people can learn only by one method, some only by the other, and some by either method but usually not both.  Maybe one reason some people have trouble learning to read is that they're taught by the method that is wrong for them.

Bottom line?  If I had it to do over again and I could choose, I think I would pick the sight method.  My daughter can read very fast — she can read a 200 page book in about an hour, and has no problem with comprehension.  I can read a whole lot faster than I speak, but not nearly that fast.  Also, people who don't have a voice in their head when they read, when they're watching a newscast on TV, can listen to the newscaster and read the crawl script at the bottom of the screen at the same time.  My daughter attests to this.  I can't do that.  For me, reading the crawl script blocks out the newscaster and vice-versa.

# Weight Loss

Weight Loss
Copyright (C) April, 2012 by Bob Day

It began in the late 1980's when I stepped on the scale one morning.  I weighed 175 pounds! — which is a little overweight for my 5' 8" height.  And I said, right then and right there, "That's it!!".  I was in my mid 50's, and for years my weight had been slowly increasing.  And I didn't feed good.  I felt kind of slow, sluggish, bloated, and heavy.  I could see where things were headed.  So — no more!  And I was able to make it stick.

For years my weight went up and down between the high 160's and the mid 150's, but never again did I weigh 175.  But I still wasn't happy with my weight, and around 1997 I set a goal of losing one quarter of my highest weight.  So my goal became to get down to 131 pounds.  Totally arbitrary?  Yes.  Why one quarter of my weight?  I don't know.  But that was my goal — 131 pounds. It took 5 or 6 years.  When I got down to 140, friends would sometimes tell me that I was too thin.  One person was concerned that I might have anorexia.  I ignored them all.  When I got down to 135, that last 4 pounds was very difficult — it took more than another year.  But I finally did it.  And now I've been under 130 for a couple of years.  I have stayed between 125 and 130, a few pounds above underweight.

Here are some things I learned:
1)  Gaining weight after middle age is not the inevitable process that the therapy world have you believe it is.  You don't have to gain weight if you don't want to.

2)  Weight loss gets easier as you go along.  Your diet just becomes the way you eat  — part of your normal life style.

3)  Calories aren't everything — Calories are the only thing!  If you burn more calories than you take in, you will lose weight.  Exercise has a whole lot of benefits, but it isn't necessary for weight loss.

1)  Three meals a day; no snacks, and no "in between" meals.

2)  Give up sugar.  No sugar in coffee, soda, or on cereal.  Give up fruit juice — it's mainly just another form of sugar.  Water is the only liquid you need.

3)  No alcohol.  Alcohol has no food value, alcohol is just empty calories.

4)  Measure the amounts of foods you eat by weighing them on a scale.

5)  Establish a very regulated diet that controls the calories you take in.  It's much easier to follow a diet that doesn't require you to be constantly counting calories.

6)  Round out your diet with supplements for nutrients that your diet does not contain enough of.

# Free Will

I have been reading Sam Harris's latest book, "Free Will", in which he
claims that free will does not exist.  Basically, he refers to some scientific
studies that show that all actions that you consciously decide to take
have actually been decided for you, totally unconsciously, in your
unconscious mind a few hundred milliseconds, or sometimes a few
seconds, before it enters into your conscious mind and you "decide" to
conscious decision is an illusion — you actually had no free will about it.

Harris is aware of the idea of quantum uncertainty, and acknowledges
that Martin Heisenberg, a biologist, has found that certain processes in
the brain occur quantum randomly (thus truly randomly), but says that
has nothing to do with free will.

But I think it may.  Consider this example, which is based on an actual
experience I had in solving a problem:  I had previously noticed that
when you heat a UPS label on a package with a hair dryer and peel it
off, it leaves a sticky area where the label was.  My problem was to
figure out how to get rid of the stickiness.

I don't know much about how the brain works, but as far as I know, there
is nothing to contradict the hypothetical mechanism I will suggest.  And
it coincides with my thinking process in solving the problem:  When you
are trying to solve a problem, perhaps there is an unconscious
mechanism in the brain that generates possibilities at random,
randomly cranking through and randomly associating past events,
objects, tools, materials, devices, et cetera that you know about.  And
when it finds an association that might relate to your problem, presents
it to your conscious mind for further consideration.  In my case of how
to get rid of the stickiness here's how it might work:

My thinking process:
How to get rid of the stickiness???  — think… think… think… (unconscious
mind cranking out a possibility).  Conscious mind:  Aha!  Try rubbing it with
a white pencil eraser.  Hmm — no, that sounds like it would just rub the
sticky around, but not get rid of it.

So,   — think… think… think…
(unconscious mind generating another random possibility).  Conscious
mind:  Aha!  Try spreading glue over the stickiness and letting it dry.
Hmm — Maybe.  I have some Elmer's white school glue, I'll try that. …
No — sorry — it didn't work.

Back to   — think… think… think…
(unconscious mind generating yet another random possibility).
Conscious mind:  Aha!  Try rubbing over it with a wax candle.  Hmm —
interesting.  Strange, but who knows?  So try it. … Yes!  Amazing.  It
worked perfectly!  Problem solved.

That's a pretty good description of how my thinking went in my
conscious mind.  Of course, I have no idea what actually went on in my
unconscious mind.  But where do these ideas that just pop into your
head come from?  Especially the one about the wax candle.  The few
candles I even own have been sitting on a back shelf for several years,
untouched.  I haven't even the vaguest (conscious) clue about where
that idea came from.

But, if there is a part of your unconscious mind that randomly
generates ideas for your conscious consideration and decision as to
whether or not to act on, I think that would be an example of free will.

# How to Lose Weight: Calories Aren’t Everything

… Calories are the only thing.  If you burn more calories than you take in you will lose weight — beginning, middle, and end of story.  Maintaining a negative calorie balance is the only thing that matters for weight loss.

The therapy professions and pharmaceutical companies would have you believe that obesity is an uncontrollable disease or an addiction.  They want you to pay for therapy or buy their drug.  Both are total nonsense.

But, losing weight is difficult.  It's a long, lonely, and solitary road.  It's not just a matter of going on a diet for a while, and it requires changing much more than just your diet.  It requires a permanent change in lifestyle, including discarding friends who disparage or try to discourage your efforts.  You, yourself, inside your soul, have to decide that losing weight is something you want to do.  Not because friends said you should lose some weight; not because your doctor is on your case about it.  You look at yourself in the mirror and decide you don't like the way you are and decide that you want to change your life.

I know all this for a fact.  I've lost over 50 pounds, gone from being overweight to being a few pounds above underweight, and have kept it off for more than ten years.

Caveats
1)  Diet Programs like Weight Watchers can help you to find a weight losing diet, but not for support.  If you need support from others, you'll probably fail.  Your desire to lose weight, which requires establishing a new, permanent, lifestyle, must come from within.

2)  Gaining Weight as you get older you're older is *not* inevitable. It's just another excuse.

3)  Exercise has many health benefits, but it is not necessary for weight loss.  It can help only if you don't use exercise as an excuse to eat more.

Recommendations

1)  Eat mostly to get the nutrition your body needs, and less for enjoyment.  Establish a healthful diet and learn to enjoy healthful foods, and make eating less a part of your life.

2)  Three meals a day: breakfast, lunch, and dinner.  That's it.  No snacks, and no "in between" meals.

3)  Give up sugar.  No sugar in coffee, soda, or on cereal.  Give up fruit juice — it's mainly just another form of sugar.  Water is the only liquid you need.

4)  No alcohol.  Alcohol has no food value, alcohol is just empty calories.

5)  In the beginning, establish a very regulated moderate calorie diet.  Don't follow any sort of fad.  Just pick a selection of foods that add up to a normal balanced diet  — whole grains, veggies, fruit, dairy, a little meat, etc.  But start out by having exactly the same three meals each day — the same foods and the same amounts.  Weigh the portions on a scale.  Consider frozen dinners.  Healthy Choice, Lean Cuisine, Kashi, Smart Ones, and probably other brands have several that are low in calories (350 or less) and saturated fat, 25% daily value or less of sodium, and high in fiber — no need to weigh these.

6)  Round out your diet with supplements for nutrients that your diet does not contain enough of.

7)  Weigh yourself every day on a 0.2 lb. accuracy scale.  Your weight will fluctuate, but with a constant diet it should trend down over every two or three days.  If it doesn't, eliminate items from your diet or reduce the size of portions until your weight does go down.  (If you don't have a 0.2 lb. accuracy scale, I'd recommend the EatSmart Precision Plus Digital Scale, which is sold on Amazon.)  Don't obsess over the scale — let it be your friend and point the way to a weight losing diet.

8)  When you have achieved a weight losing diet, then you can start making adjustments to add variety, but make sure that you keep losing weight.

9)  Establish a routine of regular daily exercise.

10)  When you're down to the weight you want to be, you can adjust this diet to be a weight maintaining diet.  Make changes for variety, but keep to the approach to eating recommended here.  That can be your permanent diet for life.  Eat mainly to get the nutrition your body needs and less for pleasure  — find pleasure in other things.
