Interviu realizat de Clarice Dinu, Ionuț Baias
Imagine si montaj Alexandru Radulescu
Filmat cu echipamnent Nikon (www.nikonisti.ro)
Are Cosmosul mai mult de trei dimensiuni spatiale? Afla, urmarind inregistrarea emisiunii Stiinta in Cuvinte Potrivite, cu Corina Negrea si Dan Manolache, din 11 octombrie. Am discutat despre detectia cu unde gravitationale a fuziunii dintre doua stele neutronice, ce ar scoate la iveala dimensiuni aditionale ale spatiului.
Sir Michael Atiyah este matematicianul englez (89 de ani) care anunța recent că a rezolvat celebra ipoteză Riemann (premiu 1 milion $). După ce și-a prezentat calculele, matematicienii au căzut de acord: calculele lui nu sunt o demonstrație, deci premiul rămâne în picioare.
Acum, Sir Michael Atiyah “lovește” din nou, de data aceasta in fizică. Într-un alt articol (https://goo.gl/oQyubJ), el susține că a găsit un principiu prin care se pot deduce constantele “fundamentale” din fizica, și exemplifică cu calculul constantei de structura fina (~1/137). (…) . Dar chiar o fi corect?
Va invit sa urmariti prima parte a conferintei “Fizica in cautarea adevarului”, pe care am tinut-o la Iasi. Organizator a fost Centrul de Cercetare Interdisciplinara in Religie, Filozofie si Stiinta. Partea a doua este aici: https://www.youtube.com/watch?v=Sge6Lv1lkZA&fbclid=IwAR0wOxfW3fR_D4940Slz92ung-F67oKhxe2QQECVBQ4r64FLmHs_x-_wOFQ
Va invit sa urmariti partea a doua a conferintei “Fizica in cautarea adevarului”, sustinuta la Iasi. Organizator a fost Centrul de Cercetare Interdisciplinara in Religie, Filozofie si Stiinta. O discutie intre Cristian Presura si Cristian Sorin Mihalache. Partea I este aici: https://www.youtube.com/watch?v=ds7xnPuYo4I
Nobelul in fizica l-a primit Gerard Mourou, pentru o tehnica de amplificare a pulsurilor laser care se numeste “Chirped pulse amplification”. In romana, “chirped” inseamna “ciripit”. De unde si pana unde? Incerc sa explic in inregistrarea de mai jos. Imi cer scuze pentru greselile gramaticale, am inregistrat totul “dintr-un foc”, nu am citit vreun text si, gandindu-ma la idei, am mai incurcat cuvintele.
What would the outcome be if you took a leap of faith straight into a black hole? We looked to Einstein and Hawking to ponder the scenario.
Say one day you were exploring space looking for a new planet for humans to inhabit, but came across a black hole and decided – why not check it out? Would you have any chance of survival? How would you get out if at all? Would you find a shortcut to another universe? Watch the video to learn about what would happen if you fell into a black hole.

“Imagination will often carry us to worlds that never were. But without it, we go nowhere.” — Carl Sagan
The Coriolis effect says that anytime you’re rotating—whether it’s on a playground toy or your home planet—objects moving in straight lines will appear to curve. This bizarre phenomenon affects many things, from the paths of missiles to the formation of hurricanes.
You may have heard that the Coriolis effect makes water in the bathtub spiral down the drain in a certain way, or that it determines the way that a toilet flushes. That’s actually wrong.
Although, as you may have noticed while tracking a hurricane on the news, storms in the Northern Hemisphere spin counterclockwise, while those in the Southern Hemisphere spin clockwise. Why do storms spin in different directions depending on their location? And why do they spin in the first place? The answer is the Coriolis effect.

Gérard Mourou, “parintele” laserului ELI NP de la Magurele, a primit azi premiul Nobel in fizica, impreuna cu Donna Strickland (studenta lui Ph.D) si Arthur Ashkin (inventatorul “pensetei optice”). Mai multe in emisiunea Stiinta in Cuvinte Potrivite de mai jos (imi cer scuze pentru decalajul video intre mine si cei din studio, Corina Negrea si Dan Manolache).
Curiozitatea, povestea şi ecuaţiile sunt coloana vertrebrală a fizicii. Curiozitatea este scânteia care, odată ce pătrunde în creier, declanşează o reacţie în lanţ. Aşa cum ştim de la copii, curiozitatea este satisfăcută prin poveşti. Acesta este al doilea pas. Deși frumoase, poveștile nu descriu cantitativ și precis natura. De aceea, pentru a încheia povestea, trebuie să învățam să folosim matematica, limbajul universal al naturii. „Fizica este o cale de a te descoperi pe tine insuti”, asa cum ne marturiseste Cristian Presura.
Fiind unul dintre cei mai cunoscuti fizicieni romani contemporani, Cristian Presura s-a descoperit pe sine prin fizica. Nascut in 1971 acesta a studiat Fizica la Universitatea din Bucuresti. Dupa terminarea studiilor a lucrat la Intitutul de Fizica Atomica unde a studiat proprietatile laserelor in medii active si solide.
A caracterizat proprietatile optice ale sistemelor corelate de electroni, obtinadu-si astfel doctoratul in fizica la Universitatea Groningen din Olanda în anul 2002. In urma cercetarilor sale, Cristian a publicat rezultatele descoperite în numeroase lucrari publicate in reviste de specialitate precum : Science.
In prezent Cristian este dedicate domeniului cercetarii si doreste sa aduca inovatie prin descoperirile sale. Acesta lucreaza ca cercetator la compania Philips si este specializat in sensozi medicali. Alaturi de echipa sa, a inventat primul ceas ce poate masura pulsul sportivilor exclusiv pe baza sensorilor optici. Cristian Presura este totodata membru al asociatiei cercetatorilor romani Ad Astra.
Dedicarea lui Cristian pentru cercetare nu se opreste aici. Acesta a publicat de-a lungul carierei sale zeci de lucrari si brevete, una dintre cele mai cunsocute fiind volumul “Fizica povestita”, o lucrare distinsa ce a fost premiata cu Premiul Academiei Romane in domeniul stiintelor fizice.
Din dorinta de a populariza stiinta si in particular fizica, Cristian este fondator al asociatiei Stiinte pentru Toti. This talk was given at a TEDx event using the TED conference format but independently organized by a local community. Learn more at https://www.ted.com/tedx

#1. Speed of sound: Unlike light, sound needs a medium to travel through, and its speed depends on characteristics of that medium like density and temperature. In the extreme environment of a neutron star’s core, sound can travel extremely fast. But knowing that sound can’t surpass the speed of light, physicists can narrow down their models of neutron stars to include only those where “extremely fast” is less than light speed.

Scientists may have found clues to the nature of dark matter in a signal from the universe’s first stars.

Here is the research paper: https://www.nature.com/articles/nature25792
Authors: Judd D. Bowman, Alan E. E. Rogers, Raul A. Monsalve, Thomas J. Mozdzen & Nivedita Mahesh
This evidence seems to suggest that the dark matter is particles that are less than four times the mass of a proton and are moving at non-relativistic speeds. This is consistent with dark matter particles being so-called WIMPs: https://en.wikipedia.org/wiki/Weakly_interacting_massive_particles.
