Roaring into 2018 with Another Big Release: Launching Version 11.3 of the Wolfram Language & Mathematica

The Release Pipeline

Last September we releasedVersion 11.2of theWolfram LanguageandMathematica——各种各样的新功能,including 100+ completely new functions.Version 11.2 was a big release.But today we've got a still bigger release:Version 11.3那among other things,includesnearly 120 completely new functions.

This June 23rd it'll be 30 years since wereleased Version 1.0, and I'm very proud of the fact that we've now been able to maintain an accelerating rate of innovation and development for no less than three decades.Critical to this,of course,has been the fact that we use theWolfram Languageto develop the Wolfram Language—and indeed most of the things that we can now add in Version 11.3 are only possible because we're making use of the huge stack of technology that we've been systematically building for more than 30 years.

11.3We've always got a large pipeline of R&D underway,and our strategy for .1 versions is to use them to release everything that's ready at a particular moment in time.Sometimes what's in a .1 version may not completely fill out a new area,and some of the functions may be tagged as "experimental".But our goal with .1 versions is to be able to deliver the latest fruits of our R&D efforts on as timely a basis as possible.Integer (.0) versions aim to be more systematic,and to provide full coverage of new areas,rounding out what has been delivered incrementally in .1 versions.

In addition to all the new functionality in 11.3,there's a new element to our process.Starting a couple of months ago,we beganlivestreaming internal design review meetingsthat I held as we brought Version 11.3 to completion.So for those interested in "how the sausage is made",there are nowalmost 122hours of recorded meetings,from which you can find out exactly how some of the things you can now see released in Version 11.3 were originally invented.And in this post,I'm going to be linking to specific recorded livestreams relevant to features I'm discussing.

What's New?

OK,so what's new in Version 11.3?Well,a lot of things.And,by the way,Version 11.3 is available today on bothdesktop(Mac,Windows,Linux) and theWolfram Cloud.(And yes,it takes extremely nontrivial software engineering,management and quality assurance to achieve simultaneous releases of this kind.)Continue reading

Showing Off to the Universe: Beacons for the Afterlife of Our Civilization

The Nature of the Problem

Confused alien with Spikey
Let's say we had a way to distribute beacons around our solar system (or beyond) that could survive for billions of years,recording what our civilization has achieved.What should they be like?

It's easy to come up with what I consider to besophomoric answers.But in reality I think this is a deep—and in some ways unsolvable—philosophical problem,that's connected to fundamental issues about knowledge,communication and meaning.

Still,a friend of mine recently started aserious effortto build little quartz disks,etc.,and have them hitch rides on spacecraft,to be deposited around the solar system.At first I argued that it was all a bit futile,but eventually I agreed to be an advisor to the project,and at least try to figure out what to do to the extent we can.

But,OK,so what's the problem?Basically it's about communicating meaning or knowledge outside of our current cultural and intellectual context.We just have tothink about archaeologyto know this is hard.What exactly was some arrangement of stones from a few thousand years ago for?Sometimes we can pretty much tell,because it's close to something in our current culture.But a lot of the time it's really hard to tell.

What Do I Do All Day?Livestreamed Technology CEOing

Thinking in Public

I've been CEOingWolfram Researchfor more than 30 years now.But what does that actually entail?What do I end up doing on a typical day?I certainly work hard.But I think I'm not particularly typical of CEOs of tech companies our size.Because for me a large part of my time is spent on the front lines of figuring out how our products should be designed and architected,and what they should do.

Thirty years agoI mostly did this by myself.But nowadays I'm almost always working with groups of people from our 800 or so employees.I like to do things very interactively.And in fact,for the past 15 years or so I've spent much of my time doing what I often call "thinking in public": solving problems and making decisions live in meetings with other people.

I'm often asked how this works,and what actually goes on in our meetings.And recently I realized: what better way to show (and perhaps educate) people than just tolivestreamlots of our actual meetings?So over the past couple of months,I've livestreamed over 40 hours of my internal meetings—in effect taking everyone behind the scenes in what I do and how our products are created.(Yes,the livestreams are alsoarchived.)

What Is a 金宝博188投注Computational Essay?

A Powerful Way to Express Ideas

People are used to producing prose—and sometimes pictures—to express themselves.But in the modern age of computation,something new has become possible that I'd like to call the金宝博188投注computational essay.

I've been working on building the technology to support 金宝博188投注computational essays for several decades,but it's only very recently that I've realized just how central 金宝博188投注computational essays can be to both the way people learn,and the way they communicate facts and ideas.Professionals of the future will routinely deliver results and reports as 金宝博188投注computational essays.Educators will routinely explain concepts using 金宝博188投注computational essays.Students will routinely produce 金宝博188投注computational essays as homework for their classes.

Here's a very simple example of a 金宝博188投注computational essay:

Are All Fish the Same Shape if You Stretch Them?维多利亚的故事On Growth and Form

Is there a global theory for the shapes of fishes?It's the kind of thing I might feel encouraged to ask by myexplorations of simple programsand theforms they produce.But for most of the history of biology,it's not the kind of thing anyone would ever have asked.With one notable exception: D'Arcy Wentworth Thompson.

And it's now 100 years sinceD'Arcy Thompsonpublished the first edition of his magnum opusOn Growth and Form—and tried to use ideas from mathematics and physics to discuss global questions of biological growth and form.Probably the most famous pages of his book are the ones about fish shapes:

When Exactly Will the Eclipse Happen?A Multimillenium Tale of Computation

Preparing for August 21,2017

On August 21,2017,there's going to be a total eclipse of the Sun visible on a line across the US.But when exactly will the eclipse occur at a given location?Being able to predict astronomical events has historically been one of the great triumphs of exact science.But in 2017,how well can it actually be done?

The answer,I think,is well enough that even though the edge of totality moves at just over 1000 miles per hour it should be possible to predict when it will arrive at a given location to within perhaps a second.And as a demonstration of this,we've createda websiteto let anyone enter their geo location (or address) and then immediately compute when the eclipse will reach them—as well as generate many pages of other information. pages

High-School Summer Camp: A Two-Week Path to 金宝博188投注Computational Thinking

The Summer Camp Was a Success!

How far can one get in teaching 金宝博188投注computational thinking to high-school students in two weeks?Judging by the results of this year'sWolfram High-School Summer Campthe answer is: remarkably far.

I've been increasingly realizing what an immense and unique opportunity there now is toteach 金宝博188投注computational thinkingwith the whole stack of technology we've built up around theWolfram Language.But it was a thrill to see just how well this seems to actually work with real high-school students—and to see the kinds of projects they managed to complete in only two weeks.

The Practical Business of Ontology: A Tale from the Front Lines

The Philosophy of Chemicals

"We've just got to decide: is a chemical like a city or like a number?"I spent my day yesterday—as I have for much of the past 30 years—designing new features of theWolfram Language.And yesterday afternoon one of my meetings was a fast-paced discussion about how to extend the chemistry capabilities of the language.

At some level the problem we were discussing was quintessentially practical.But as so often turns out to be the case for things we do,it ultimately involves some deep intellectual issues.And to actually get the right answer—and to successfully design language features that will stand the test of time—we needed to plumb those depths,and talk about things that usually wouldn't be considered outside of some kind of philosophy seminar.

Oh My Gosh,It's Covered in Rule 30s!

A British Train Station

A week ago a new train station,named "Cambridge North",opened in Cambridge,UK. Normally such an event would be far outside my sphere of awareness.(I think I last took a train to Cambridge in1975.) But last week people started sending me pictures of the new train station,wondering if I could identify the pattern on it:
