Tijd in machten van Tien,
door Gerard ’t Hooft en Stefan Vandoren, Uitgave Natuurwetenschap &
Techniek, onderdeel van Uitgeverij Veen Magazines B.V.
Time in Powers of Ten, by G. t Hooft and Stefan Vandoren, translated by Saskia ’t Hooft - Eisberg. World Scientific. The idea is simple: Physicists and astrophysicists have produced various popularized descriptions of the enormously varying length scales in the Universe, in books and films. The Universe is some 50 billion light years across, that's nearly 1029 cm. The smallest conceivable objects are superstrings, somewhere around 10-32 cm. At every scale in powers of ten, our world looks different and very special. So now, we do the same thing with time. In fact, the variations in the time scales are even bigger. The time scale for super strings is 10-43 seconds, and age of the Universe is less than 1018 seconds, but there are phenomena that outlast our Universe by gigantic factors. The lifetime of the most fundamental particle in our world, the proton, is expected to be something around 1041 seconds, and large black holes can last much longer than that. At nearly every time scale, things happen in our world, and we describe them, starting with just one second, then 10 seconds, 100 seconds and so on, until in the middle of the book, where we switch to the fastest time scales conceivable, until at the end we return to one second.
Taming the forces between Quarks and gluons - Calorons Out of The Box/a>, Scientific Papers by Pierre van Baal, eds G. 't Hooft and C.P. Korthals Altes, Wold Scientific. Book presented at the Lorentz Institute, Leiden June 21, 2013.
The English translation of "Planetenbiljart" has appeared. English title: "Playing with Planets" (World Scientific, Singapore). See http://www.worldscibooks.com/general/6702.html. The original text has been improved in many ways. Translation by my daughter Saskia.

May, 2013: A few more tesselations
Figure at left: the "Peaucellier–Lipkin linkage". See "Meccano Mathematics I", a little treatise on some nice features of meccano strips. For those who like Meccano and Euclidean geometry at shigh school level. Meccano Math II describes the solutions to the exercises given in Meccano Math I, and more. Interesting new solutiosn (from the 19th century!) are described in Meccano Math III.
Gravitating misconceptions: response on claims by a group of self proclaimed scientists concerning the validity of the theory of General Relativity.
Taalperikelen (door G. t Hooft)
Voordracht over Professor Sickbock t.g.v. de Marten Toonder tentoonstelling in het Teylers Museum te Haarlem,1 juni 1996.
Some old documents were found when cleaning some closets:
1) Here is what Frederick Reines wrote on a napkin in a restaurant on Balboa Island, Newport Beach, California, back in 1981. And:
2) In the year 2000, at Copenhagen, many physicists were bold and optimistic about supersymmetry. Here is a wager, duly recorded. The date of "discovery of supersymmetry" was set at June 21, 2010. I would be ready to give them another six or so years, but then I will politely approach my susy friends to inquire about the bottle of cognac.
3) Brief aan Darwin (in Dutch, op uitnodiging van De Volkskrant
4) Reaction upon a letter that was sent to The New Scientist by a group of scientists who urge to establish new categories of Nobel Prizes. Later, I learned that the Nobel Committee itself reacted very much in the same spirit.
A treatise on evolution.

Complaints about MS Word®: http://www.gnu.org/philosophy/sylvester-response.html . Add to this the serious troubles with its so-called "smart quote" feature, which inverts quotation marks incorrectly. In particular, it deliberately wrecks the spelling of the family name t Hooft, where it replaces the apostrophe by a beginning quotation mark.

June 5, 2012: Honorary Doctorate from the National Polytechnical University of Odessa, Ukraine.
Boek van Lucas Ellerbroek, "Planetenjagers" (Prometheus . Bert Bakker) is aan te raden.
Exploration of the Moon and Mars. See book: "Playing with Planets".
A human settlement on Mars is possible! See Mars One...It is going to be a spectacular mission - if the plans can be realized. It all depends on how much support these plans will receive world-wide! And funding. The press conference December 10 disclosed how the plans further evolve: contracts with Lochheed Martin to develop and construct the first Mars One unmanned Mars lander, and Surrey Satellite Technology Ltd. (SSTL) for the communications satellite that will orbit Mars.
9491 Thooft has its orbit
between those of Mars and Jupiter. This asteroid was discovered March 25, 1971,
by C.J. van Houten and I. van Houten-Groeneveld on Palomar Schmidt plates taken
by T. Gehrels.
They are also the discoverers, in 1977, of asteroid 11779 Zernike, named after my grand-uncle Frits Zernike.
As illustrated by this photo, all cattle in the meadows of the Netherlands by law have to wear ear tags. My bicycle trip in the countryside inspired me to modify the bylaws of Constitution Law # 13 for 9491 Thooft-s Constitution.
An article concerning freedom of religion was added.

Special message to those who wish to mail to me their new revolutionary theories: Please first check yourBaez index, and/or consult Warren Siegel.
Another "experiment" was recently reported in which paranormal signals were claimed to be observed. Probably the flaw is an incorrect handling of the statistics, where unintentional bias was difficult to exclude. I am prepared to challenge these and any other serious investigators with a bet. See here the conditions.
