Robots, Robots, Robots - Part 1.
If you have seen a manufacturing facility in the last ten years, you have seen industrial robots. They come in all shapes and sizes, from desktop models that can move a pen or pencil, to giant hydraulic arms which can grab an automobile off of an assembly line.
In short, robots have proliferated across the globe. I can imagine a time in the not too distant future when robots will outnumber humans. I'm not talking about robotic servants in our homes that cook, clean, and wash windows, although those will certainly come to us someday. I'm talking about the robots which have largely replaced us in our factories, fly our airplanes, drive our cars, sail our ships. Did you know they can see? Yes, they now have all of our five senses: sight, touch, taste, hearing and even smell. Technology is advancing so fast it sometimes makes my head spin when I think about it.
Why should we care about the proliferation of robots (and smart computer programs)? Well, for one thing, they are putting us out of work. They don't get paid, they always show up for work, that is, they never go home. They may break down and need to be repaired, but they don't get sick unless they are connected to the internet and may be subject to hackers.
But more significantly, robots or smart computer programs may become sentient, self aware machines. Can you imagine that? Can you imagine what a robot could do with access to Google? With the ability to learn and remember everything, there is no limit to what it might do. It boggles the mind.
I once heard a professor say he would not be afraid of a robot as long as it loved him. I'm not so sure. I love my dog and my cat, but I don't think I want a robot to keep me as a pet. Do you?

Carl Sagan's Novel - Contact!
I'm reading Dr. Carl Sagan's fiction novel, Contact.
You can find the Contact book on Amazon.com here:
Click here for the Amazon.com "Contact" web page.
I love this book for several reasons. Although it tells a story, it allows Dr. Sagan to teach us a great deal of Science, particularly Astronomy which was his specialty.
Astronomy is fascinating because it is the biggest picture we can imagine. When you begin to grasp the size of the solar system, the Milkyway Galaxy, and think about our place in the Universe, it is mind blowing. It may not be infinite (according to Einstein) but it is so big it may as well be. BTW, Contact was published in 1985 and was made into a movie in 1997. Today (3/17/17) the movie is available on Netflix. I recommend it highly, particularly the first few minutes of the film which gives you the scope of the known Universe. It's tremendous computer graphics, and shows you THE BIG PICTURE!
Astronomical distances are so big astronomers have to resort to an unusual yard stick to measure it. Their yard stick is called a, "light-year". Most of us have heard of a light year, but do you know how big it is? A light year is the distance light can travel in one year. We know light travels 186,000 miles in one second, and there are 60 seconds in a minute, 60 minutes in an hour, 24 hours in a day, and 365 days in a year. Therefore, there are 60 x 60 x 24 x 365 = 31,536,000 seconds in a year. Now, multiply that times 186,000 and we should have our distance in miles.
186,000 miles per second x 31,536,000 seconds per year = 5,865,696,000,000 miles per year !!!!!
One light year is well over 5.8 Trillion miles, or if you prefer, it's over 5.8 Million Million miles, and light can travel that distance in one year.
Now the nearest star, other than our sun, is Alpha Centauri (AC). I learned in Contact that AC is approximately 4.25 light years from us. Let's do the math:
4.25 light years x 5,865,696,000,000 miles per light year = 24,929,208,000,000 miles
This means our nearest star is almost 25 Trillion miles away, and if we wanted to send a message to a planet circling AC, then it would take 4.25 years to get there and another 4.25 years for their reply to get back to us, making a round trip of 8.5 years just to say, Hello!
Let's just hope that our side of the planet is facing towards AC when the reply comes back! If we are facing away from AC when the reply message arrives, we will miss it!!! (Remember the earth rotates once each day, so it turns away from AC for 12 hours at a time.) The Earth's rotation is a problem for inter-space travel communication as well.

The Importance of Data. Science Vs Religion.
You may know data is everything to scientists and engineers. They live and die by their data. The data doesn’t lie. You can accept it or reject it, but it doesn’t
care what you think. It is what it is. It is all about truth. It tells you what is real, given your ability
to measure whatever it is you are testing.
I don’t argue with what works. You can always retest, but it is hard to argue with consistent data. You may find a way to cure the common cold,
or keep worms from eating your tomatoes, and one way may be better than another. But if it works, I just want to know two
things: 1) are there any side effects, and 2) what does
the solution cost. If there are no side
effects, then the solution is great, and if there are side effects, then I want
to know the impact. Can you live with
the side effect? For instance, if you
are testing a new cancer drug, can you keep the patient alive even if his
ankles swell up a bit? Or if you are
testing a new pesticide, will you kill an entire species of worm in order to
save your tomato crop? Will the worm-eating birds die of starvation,
or will they adapt and find another insect to eat? These are the kinds of things Science can
tell us if we work hard and smart enough.
Of course, successful business leaders use lots of data
too. They measure all kinds of factors
that contribute to their profit and loss.
Naturally, if they are wrong, or they don’t pay attention to the right
details, they will go bankrupt and lose their business. If they are right and customers love their
products or services, and if their costs are lower than their prices, they will
make money and their business will thrive.
So the bottom line is this:
we all live and die by our data. You
can think of it as the sensory information we take in and process using the one
survival gift nature has bestowed upon us, our big brains. So why, I ask do we abandon our reason, logic
and empirical data and believe in things for which there is no evidence at all? You may have guessed by now, I am writing about
Religion (with a capital ‘R’).
My own belief is that we are all too terrified of death, so many of us embrace an ideology which says we don’t really die, but we go to heaven
where we will live on forever. But is
there any evidence (data) that we have a soul?
Is there any evidence (data) for life after death or the existence of
god or heaven? Must we accept the
philosophical ramblings of a scientifically ignorant people who lived over a thousand years ago?
Do you believe in
miracles? If so, why do you believe in
them? What data do you have to support
your belief?
Many people say there are two camps of information, those
that can be supported by information (data), and those which require no
support. I reject this argument. I say we are animals, we are specifically, thinking
primates, with big brains and a limited lifespan of something less than one
hundred years. Like all the other
animals on the planet, we are born, we live, we struggle, we mate, we may
reproduce, we grow old and we die. And
like all the other animals, we will rot as bacteria then consume our bodies. If we are lucky, we will do something
important with our lives, and we may do something to help insure the long term
survival of our species on the planet.
This is the Scientific point of view, and it is in
direct contrast and opposition to the fairy tale wishful thinking world view created
by the religion camp, and by the people (primarily old men) who profit by
spreading the superstitious and ignorant words of a people who lived over a
thousand years ago.
Now don't get me wrong. I don't really fault our ancestors too much. They were just trying to make sense of life and death with the data that they had at the time. They didn't know their place in the universe. We are still trying to figure that out. But we have come a long way. We know for instance, that stars are more than points of light in the night sky. Think about it. We have put more than one of our own species on the moon and brought them back safely to earth. We have used robotic probes to explore and take pictures of the other planets (and their moons), and we have even sent spacecraft beyond our solar system. This is the stuff of Science Fiction, but we made it Science FACT. We have the data to prove it.

Expect the Unexpected! Use a Monte Carlo Simulations.
Expect the unexpected!
"How do I do that?" you ask.
Figure out what is logical to happen, and then think about what illogical thing could happen instead.
The probability of the illogical happening may be bigger than the logical. Why? Because we can't know everything. We don't know all the factors that may contribute to the problem at hand. What's worse, is that we often don't know what we don't know. Sometimes we may know the parameters but not the possible values. We have to guess at the possible values.
What's the good in guessing? Well, sometimes you may be able to specify a range of values for a guess, and you may also be able to associate a probability that a particular guess will occur.
You can do the calculation repeatedly and calculate a probability for each possible outcome.
There is a mathematical, computerized tool for doing this. It is called, a Monte Carlo Simulator and is used to calculate probable outcomes for all kinds of problems where factors are unknown and some degree of risk is involved.

Environment, Heredity & The Concept of Heaven.
Why are we the way we are? How did we each get to be the people we are?
Science has long accepted that each of us is the product of our environment and our heredity. One can argue whether environment or heredity plays the greater role in our development, but few if anyone would argue that one is exclusive over the other. Most agree that we interact with our environment based on our heredity.
If we are smart enough, we can change or manipulate our environment to be successful in our endeavors and grow and thrive as individuals. Consider a seven foot male who learns to play basketball, or a gifted female mathematician who becomes a brilliant physicist or successful computer programmer. But what would a seven foot male do in a culture without basketball? Or what would the mathematician do if she were born in the Middle Ages? One can only imagine the frustration such an individual would feel by being born in the wrong place or in the wrong time. As a case in point, what would Mozart have become if he were born into a world without a piano or even music? What would he have been if he was born into a middle eastern culture where music was banned?
But did you pick your initial environment into which you were born? Did you pick your parents? Did you pick your socioeconomic class or the fact that you were male or female, and the country or time into which you were born? The answer must be no.
It has occurred to me that we control none of those things. We didn't select our parents. We didn't select our genes (our heredity), and we didn't select our environment, our place or year in which we were born.
So, I ask an unsettling question. How is it that we can be held accountable for who and what we are? In short, we can't help but be the person who we are. Each of us is predestined to succeed or fail or die trying to do that which we feel we must as we interact with our environment. We each do the best we can with who and what we are, and what resources and opportunities we have at our disposal.
This idea turns the concept of sin on its head, and in doing so eliminates the reward or punishment for having lived a good or bad life respectively. Yes, society must protect itself from bad people who would murder, rape, rob, steal or do other terrible things, but the predestination argument kills most of the established world religions which would have us believe we will be rewarded in heaven or damned in hell for being the people we could not help but become.
What does this tell you about organized religions? What are their motives?

Would you take a Life Extension Pill?
If I offered you a pill that would make you live indefinitely, would you take it?
I used to ask this question to friends of mine, or sometimes to people I just met. Why? The answers I got were very revealing.
If the answer is that the world would become over populated if we extended life, then modern medicine is a moot point. Why bother saving lives at all if we are all going to die eventually anyway? Why not just accept death as a normal part of life and make room for the next person who was born today? Of course, I am just being facetious. My personal physician admitted to me he is just forestalling the inevitable, a fact I readily concede. But I take his medication and his medical advice seriously. Why? Because I love my life! And finally, I have to say the population argument does not hold water because we know how to prevent babies from being conceived. We know how to use birth control, and each of us can help the world by limiting the number of people being born by taking precautions with our sexuality.
If the answer is that prolonging life is not God's plan and we should accept death so we can go to heaven to be with God for all eternity, then why not embrace death and kill ourselves now? What is the point to living if it is for just a short time compared to eternity? Again, I am being facetious and argumentative. We each can and should do what we can to make the world a better place by having lived our lives as best we can.
And I don't know about you, but there is so much I want to do before I die. I love the concept of a "Bucket List" of things to see and do before we "kick the bucket" or "give up the ghost"!
What bothers me is that most bucket lists consist of places to travel or experiences like jumping out of an airplane, or eating exotic foods. My bucket list consists of becoming more than I am. For instance, I want to grow musically by learning to play improvisational jazz piano, and learn to speak Spanish fluently.
And finally, what about those we love and care about? We should do everything we can to help those we love develop into the people they want to be. I get a kick out of sharing my life with others who are happy and having a blast doing what they do.
I hope you can see I would take that life extension pill in a heartbeat. But that's just me.
What about you? What do YOU think? Leave a comment!!!

The "Theory" of Evolution
I am no longer amazed when I find otherwise intelligent adults who don't believe in evolution. Why?
Because we call evolution, "a Theory". The word, "theory" makes it seem like evolution is a guess, not a fact. But nothing could be further from the truth. We know evolution is real, not only from the fossil record of plants and animals buried in the ground all over the world, but also from current biological organisms alive and well today of which we are a part.
Yes, you got it right. Like it or not we, as a species, are evolving! A simple Google Search found a web site which lists five indications that we are still evolving! These are:
Check out the web site. Here you will find an in depth explanations of all of the above.
We Are Still Evolving
Note: I want to be clear about what evolution is. We are not evolving as individuals. Each of us fortunately or unfortunately, is stuck with the genes we are born with. We can't change them. We evolve only as the species homo-sapiens due to changing conditions in our environment.
Need More Proof?
If you need more proof, watch this documentary film on the subject. It is the best film on evolution I have ever seen!

- We have developed the ability to drink milk (process lactose).
- We are born without wisdom teeth. (They are vestigial and no longer necessary.)
- We are resisting new diseases. (Malaria, Tuberculosis, Leprosy)
- We are born with smaller brains. (Our brains are more efficient!)
- We are born with blue eyes. (A genetic paternity test.)
