witam cosmo-torun,
IOP to nie firma, która ewidentnie popiera otwarty dostęp do informacji, raczej ma tradycję zamkniętą. Jest dlaczego dla mnie, jest to raczej ,,spam".
Jednakże, artykuły mogą być interesujący - dla osoby nie chętny do szukiwanie w arxiv.org.
Np, raczej lubię artykuł Ashtekar'a: są dwa rodzaju ,,approaches" do grawitacji kwantowej
- jeden w czymś jest m.in. teoria struń (jest teoria ,,perturbative",
- drugi w czymś jest m.in. ,,loop quantum gravity" (związany z Ashtekarem)
Ashtekar uważa, że z loop quantum gravity, nie ma osobliwość na a(t) = 0, bo zwykly czas-przestrzeń tam już nie ma.
Więc, tu jest info ta.

Dear Dr Roukema
You may be interested to know that New Journal of Physics (http://www.njp.org) has just published the third of its three celebratory Focus Issues to appear this year in connection with the World Year of Physics.
All contributions to 'Spacetime 100 Years Later', edited by Richard Price and Jorge Pullin, are permanently free to read at http://www.njp.org/focus/spacetime. Each review article is also listed below with a direct link.
Please don't hesitate to contact me with any comments or queries you may have about this issue or NJP in general.
With best regards,
Tim Smith
