The Future of Humanity: Terraforming Mars, Interstellar Travel, Immortality and Our Destiny Beyond EarthThe Future of Humanity: Terraforming Mars, Interstellar Travel, Immortality and Our Destiny Beyond Earth by Michio Kaku
My rating: 4 of 5 stars

Author Booksite

As the title suggests, this is one of the books for which theoretical physicist Michio Kaku dons his futurist cap to speculate about what is to come. Other of his books that might be included in this “series” are: Visions, Physics of the Future, The Future of the Mind, and Physics of the Impossible. This particular book focuses on how humanity will spread beyond the planet (and, perhaps, beyond the universe) to survive the (probably distant, but – also – inevitable) threats to the species. While there are other topics discussed, such as the search for immortality and transhumanism, those topics are often framed as necessities of interstellar expansion.

As one would expect of a physicist, the book is highly focused on the physics of the subject. There is little discussion of the psychological difficulties, nor of biological issues such as the fact that humanity is not so lone wolf as we think, and taking off to other planets and living in space without the Earthly life we are interdependent on would involve challenges we have difficult fathoming. All of the challenges that are usually treated with handwaves in science fiction are also handwaved off here.

The book is fun and interesting reading. It’s probably more insightful of science fiction than of our future, but that doesn’t make it less compelling. The seven years since this book was published have seen a lot of change, and there may be a book on this subject that has more of a finger on the pulse, but I still enjoyed reading it. [The downside of writing about the future, even with a focus on the distant future, is that one risks becoming obsolete rather quickly.]

If you’re interested in how humanity might survive into the future, I’d recommend this book. If you enjoy popular science and / or science fiction, you’ll probably find it intriguing.

List 10 things you know to be absolutely certain.

1.) Nothing is permanent.

2.) The world is not what it seems.

3.) One’s subjective experience is not determined by the state of the world.

4.) Nobody grasps enough truth to be intolerant.

5.) Uncertainty is the root of all fear.

6.) Fear is the root of all hatred.

7.) Hatred is a subjective experience (See #3.) Also, uncertainty is the root of all hatred (by the transitive property,) hence the benefit of travel.

8.) Any who: a.) has suffered a string of hardships; b.) allows themselves to believe that some “other” is wholly responsible for said hardships; and c.) who lacks a sufficient sense of self-empowerment to avoid surrendering entirely to a group identity can (and likely will) become a Nazi (or the equivalent of their day.)

9.) No one can predict the future. [Regardless of how much we all love to try. (See #5.)]

10.) Entropy increases (ultimately, in a closed system.)

NOTE: I remain ready to abandon any certainty in the face of better information.

Masala Lab : The Science of Indian CookingMasala Lab : The Science of Indian Cooking by Krish Ashok
My rating: 4 of 5 stars

Publisher Site – Penguin

Many books have come out in recent years that explore the intersection of science and cooking, but this is one of the few that I’ve seen take on the sub-theme of science’s role in a particular cuisine — in this case Indian. Indian food, while broad and diverse itself, does present a unique palette of considerations. Few cuisines can make claims to the same level of complexity as Indian with all its spices and such. Also, Indian food tends to use heat to a different extent / in different ways than other cuisines, which is partly why, while Indian food is as tasty as food gets, aesthetically it tends toward a visually unappealing gloopy-gloppyness.

Ashok examines what applied heat does to food and why, how flavors are balanced and enhanced and why, what acids do and why they are essential, what value added is gained by pressure cookers and other specialty equipment, and how an experimental approach can be taken in lieu of a recipe book? The book takes a few controversial stances, such as in favor of sodium bicarbonate and MSG, but to a large extent is a straightforward discussion of how science informs culinary technique and ingredients.

The author maintains a light and readable tone throughout the book. I’d recommend this book for readers interested in the intersect of science and food, doubly so if one has a particular interest in Indian food.

      selection will take place.

Some erroneous copies will 
    be more beloved than others.
      Some errors will propagate.
      Some errors will die out.

Thus is language,
   thus is chemistry,

Raise chaos:
   That's the job of intelligent life,
      to make nice & orderly things
      so they can crack and shatter
      and eventually end up pulverized
      to dust --
   A fine, granular dust that will blow
      across the universe.

First, the bowl must be made:
   Some potter must shape and glaze
      and fire it with care,
   Turning sandwiches into art... 
      and waste heat --
         entropy slow and fast.

All so someone can crack or chip it
   (with ease and lack of intention,)
   starting it on a path to being sand
   grains a world away.

BOOKS: The Second Law by Stephen Wolfram

The Second Law: Resolving the Mystery of the Second Law of ThermodynamicsThe Second Law: Resolving the Mystery of the Second Law of Thermodynamics by Stephen Wolfram
My rating: 4 of 5 stars

Amazon.in Page

This book has an intriguing premise but a bizarre organizational scheme. The book offers insight into the Second Law of Thermodynamics couched as the author’s personal journey of discovery. Put simply, the Second Law says that entropy increases, or the coffee cup next to me can fall and break into many pieces but it can’t / won’t reassemble itself, alternatively, I can mix milk into the coffee in the cup, but not unmix the milk out of it. Of course, this simplification is — in fact — a massive oversimplification and there are a number of definitions of entropy and different ideas on the conditions under which its increase holds and why. This is part of what the book investigates.

Let’s start with the book’s intriguing premise. It is that: a.) the Second Law and its implications are not as well (or fully) understood as the scientific consensus suggests, and b.) the key to understanding entropy’s increase may be found in the concept of computational irreducibility. This all ties to Wolfram’s work with cellular automata and the finding that apparent randomness can come about from a simple set of rules that are non-random. In other words, cellular automata could produce a pattern that can only be determined by re-running said simple set of rules — i.e. there would be no way to compute it. As (apparent) randomness plays an important role in the Second Law, Wolfram proposes a connection that has ramifications for critical issues like reversibility. (Remember we can’t unmix the milk out of the coffee [without expending more energy and within the confines of an open system] or so it’s believed.)

When I say the book’s organization is strange, I do so with the assumption that the intended readership includes those who are scientifically literate but not expert in thermodynamics or physics. The first part of this strangeness is that the body of the book concludes with an overview of the development of the Second Law (arguably this is information a non-expert reader might benefit from having up front.) The second element of strangeness is that much of the latter part of the book is just connective tissue between excerpts of other people’s writing on the subject. This increases the page count tremendously and doesn’t serve readability well.

The book does have a good deal of interesting and informative graphics. It also has copies of scholarly papers and relevant chapters from Wolfram’s previous book, “A New Kind of Science” for those who are capable of, and interested in, taking a deeper dive into the science and mathematics under consideration.

I found this book to be thought-provoking if a bit tedious to read in places. If you’re interested in the Second Law, it’s worth reading and may shed new light on the topic.

What was your favorite subject in school?

Depends on the year. In twelfth grade, I remember enjoying Physics the most. In Eleventh, Psychology was the best class I attended. There was a year when I got the most out of an English class that focused on Creative Writing. I guess my most longstanding preference was for classes like Geography and Social Studies, wherein we learned about the world outside our world.

PROMPT: Topics

Which topics would you like to be more informed about?

I’d love to know why the fundamental equations and constants that govern the universe appear to be tailor-made to generating life?

I’d love to know whether there is other intelligent life in the universe, and – if not – why not? (And, if so, have they visited, are they visiting, do they intend to visit, and – if none of the above – why not?)

I’d love to know whether there is meaning to life other than moving energy to higher states of entropy in a Sisyphean fashion (and any other meaning that one independently chooses for one’s self?)

But I’m doubtful any of that will be clarified in my lifetime, so I guess I’ll have to stick to more down to earth topics, such as: “Is ‘a good life’ a meaningful statement, and – if yes – how does one go about pursuing one.”

What's this world?

It's energy playing a game,

  a game whose goal is to be rid
    of an intense burning sensation,

  a burning sensation caused by
     low-entropy energy sitting
     around with nothing else to do
     but burn brightly. 
  
  We, the wasters of energy, are 
     a soothing lotion to the universe,

     expediting the making high-entropy, 
          soothing, tepid energy from 
          all those stars -- 
          i.e. the universe's poison ivy.
