  Carl Theodor Dreyer
A departure from Carl Theodor Dreyer's general reputation as a director of severe, forbidding, and deeply spiritual films, Master of the House reflects the gentle humor, humanism, and innate social conscience that is often overlooked in the cursory assessment of Dreyer's stylistically identifiable and accomplished body of work.
Using parallel imagery that further reflects a distinctive aspect of Dreyer's art, the film underscores the characters' profound transformation towards empathy, self-reliance, and equality: the resigned and methodical performance of chores; Viktor's contrasted behavior towards Ida's pet birds; the repeated ritual of parent and child folding a blanket.
Dreyer further uses episodic recurrences to inferentially develop the plot while retaining the visual economy of the film.

 Olaf Dreyer: the Cosmological Constant paradox
Olaf Dreyer is maybe not the main player here---he's a young person at Perimeter who takes risks.
Olaf Dreyer is involved in another controversial issue besides the Cosmo.
Now we move on to fl holes and try to see why Olaf Dreyer (and others) say that it has to be scaled down still further by the Immirzi.

 | Geschichte
Seit 1992 ist der Kamerad Olaf Dreyer der Jugendwart der JF Rensefeld.
Aktuelle Beispiele für eine „Feuerwehrkarriere“ aus der Jugendfeuerwehr sind der heutige Ortswehrführer Joachim Kendziorra, der Schriftführer Udo Loddoch, die Gerätewarte Volker Andersson und Christian Szarata, die Gruppenführer Rainer Krug, Olaf Dreyer und als erste Frau in diesem Amt Cornelia Piper.
Insgesamt wurde diese hohe Auszeichnung sechsmal an Jugendwarte der JF Rensefeld verliehen: Günter Nell bekam die Spange in Gold, Gerhard Andersson, Olaf Dreyer und Heino Mustin in Silber, Monika Lackner und Stefan Bollmann bekamen sie in Bronze.

 Guide to Reality: Geometrogenesis
She goes on to credit Olaf Dreyer (see this paper, for instance) and quantum computational theorist Seth Lloyd (see here) for advocating this concept of emergence with regard to dynamical space-time.
Dreyer tries to give an intuitive story on this.
Two internal observers who are themselves at the emergent scale cannot detect their motion against the micro-background, so they will attribute the same speed to an observed emergent particle.

 Quantization of area: the plot thickens
But now, thanks to work of Olaf Dreyer [1] and Luboš Motl [2], two very different methods of calculating the quantum of area have been shown to give the same answer:
In November 2002, Dreyer [1] found an ingenious way to reconcile Hod's result with the loop quantum gravity calculation.
With the appearance of Dreyer's paper, the suspense became almost unbearable.

 Quantization of Area
At this point the suspense became almost unbearable: Hod's observation relied on numerical calculations, so the very next digit of his number might fail to match that of 4 ln(3).
Luckily, soon after Dreyer's work, Motl [2] showed that the match is exact.

 Press Release for The Trouble with Physics published by Houghton Mifflin Company
Olaf Dreyer is a bold, deep, and extremely independent thinker who has made new proposals for solving the key foundational issues, including the measurement problem in quantum mechanics, the nature of fl hole entropy, and the problem of the cosmological constant.
Olaf got his Ph.D. at Penn State University in 2001, and after a period at Perimeter Institute is now a Marie Curie Fellow at Imperial College, London.
Laurent Freidel has quickly become one of the most influential physicists working on an approach to quantum gravity called spin foam models.

 Edge: LOOP QUANTUM GRAVITY
When we first did this kind of calculation, in the mid-1990s, we got the entropy right up to an overall constant.
A few months ago, in a brilliant paper, Olaf Dreyer, a postdoc at the Perimeter Institute, found a very simple and original argument that fixes that constant, using a completely classical property of fl holes.
He uses an old argument of Neils Bohr called the correspondence principle, which tells us how to tie together classical and quantum descriptions of the same system.

Olaf Dreyer finds that the bizarre and humongous discrepancy in QFT vacuum energy arises from the theory not having been formulated in a Background Independent way.
He gives a short argument as to why QFT, once it is made B.I., would not have a problem with the cosmological constant.

 Loop quantum gravity
These heated debates did not preclude scientific collaboration of sorts.
After Baez announced in his column "This Week's Finds in Mathematical Physics" that Olaf Dreyer had found a connection between the Immirzi parameter and the asymptotic behavior of fl hole quasinormal modes (in numerical general relativity), Lubos Motl wasted no time proving that the exact asymptotic behavior was as predicted numerically.
Hopefully, experimental results as early as 2007 to 2010 may help guide researchers and funding.

Three weeks later or so, I received an e-mail from her or him that stated that the problem of the value of "gamma" had been solved.
The solution was written in a provoking paper by Olaf Dreyer which was equivalent to the following argument:
If we change the gauge group from SU(2) to SO(3), then the minimal allowed "j" in the spin network will be "j=1" which carries three polarizations, i.e.
