De la istoricul Herodot se Čtia cum s-au construit piramidele: nu au fost extratereČtrii, ci zeci de mii de sclavi care munceau, pentru o piramidÄ, 20 de ani! Foloseau rampe Či alte mecanisme inginereČti ale vremii lor, pentru a urca Či pune blocurile de piatrÄ unul peste altul. Dar cum ajungeau blocurile de piatrÄ, masive, acolo, de la mari distanČe? Recent, arheologii americani au gÄsit rÄspunsul: folosind un braČ maritim al fluviului Nil, necunoscut pĆ¢nÄ acum. Privit aici harta. Ćn dreapta este Nilul. Linia albastrÄ, punctatÄ, din stĆ¢nga este locul prin care, acum cinci mii de ani, trecea un braČ al Nilului. RemarcaČi cum acesta trecea pe lĆ¢ngÄ locurile unde s-au construit cele mai mari piramide. Ei bine, pe el erau transportate marile blocuri de piatrÄ Či alte lucruri necesare constructorilor. BraČul a secat de atunci, iar urmele lui sunt ascunse Ć®n terenurile agricole de azi. Arheologii le-au gÄsit folosind sÄpÄturi specifice Či mÄsurÄtori din satelit. Se poate ca de-a lungul acestui braČ de apÄ, azi secat, sÄ existe Či alte construcČii ascunse Ć®n pÄmĆ¢nt. Desigur, poate sÄ scrie Herodot ce vrea Či arheologii moderni sÄ gÄseascÄ orice, asta nu va opri niciun conspiraČionist sÄ pretindÄ cÄ piramidele au fost construite de extratereČtri”

Join Ariane 6 launch system architect, Tina, as she shows us a day in her life.
Tina has worked on space transport systems for 20 years now. She first worked on the Automated Transfer Vehicle (ATV), then on the Ariane 5 Mid-life Evolution development and now on Europeās newest launcher Ariane 6.
How did she become a rocket scientist?
āI was lucky enough to spend some months in French Guiana as a student for an internship and working there got me hooked ā I was determined to come back for my job one day, and here I am: I spent a great part of 2023 in Kourou testing the Ariane 6 propulsion system, together with an amazing team of very skilled professionals.
I consider myself extremely lucky to have a job and colleagues that make me want to get out of bed and into the office every day ā because we love what we do and because the people are simply amazing!ā
Hold onto your hats, because Science Max is taking you on a high-octane ride through the science of transportation! This epic compilation throws you into the driver’s seat of three incredible experiments. First, Phil tackles the science of stored energy by building a giant (we’re talking giant!) spool racer. Can he harness enough power to make it zoom? Next, we dive into the watery world of propulsion with a massive, 500-liter water-powered car! Buckle up as Phil pushes the limits (and gets soaked!). Finally, Phil gets his dragster on in a high-speed experiment that uses inertia to take things to the max. Get ready for mind-blowing science, epic fails (hey, that’s science too!), and maybe even a pumpkin carving demonstration with a pressure washer (seriously!). This episode is guaranteed to get your motor running!

#stiinta #fizica #science #tehnologie #technology #cristianpresura “Ce vedem aici este o “ploaie solara”! In partea de jos este suprafata Soarelui. In partea de sus este atmosfera Soarelui, denumita si corona sau coroana, in termeni populari. Doar ca amosfera Soarelui, care se intinde pe milioane de kilometri, este facuta din plasma, in cazul de fata un gaz puternic ionizat. Asta se vede foarte bine in pozele cu eclipse de Soare. Plasma, din care este facut atmsofera Soarelui, ascunde un mister: temperatura ei este de milioane de grade Celsius, desi suprafata Soarelui are doar 6000 de grade Celsius. Cum se poate?In mod normal, cand ne indepartam de foc, temperatura scade.iata misterul nerezolvat! In imagine vedem cum plasma din atmsofera se raceste si cade apoi catre suprafata Soarelui, in linii luminoase, despre care se crede ca urmeaza liniile de camp magnetic. Mai vedem pe suprafata Soarelui tot felul de structuri ce fac parte din cromosfera, care este partea de jos a atmsoferei Soarelui, de doar cateva mii de kilometri inaltime. Cromosfera este interfata dintre Soarele ce “bolboroseste” si atmosfera lui. Aici se initiaza eruptiile solare. Un lucru e cert daca privim din nou aceasta “ploaie” de pe Soare: nu ne va racori! “
A group of 12 volunteers are sticking to a strict bed routine for 60 days, lying with their feet up and one shoulder always touching the mattress. This reclined lifestyle includes meals, showers and toilet breaks, as well as intensive cycling and centrifuge rides for some.
The BRACE study follows a two-month bedtime schedule to investigate how cycling and artificial gravity could counteract changes the human body experiences in space.
Astronauts face similar physiological problems as elderly and bedridden patients on Earth. During space missions, astronautsā bodies go through a wide array of changes ā everything from their eyes to their heart might be affected, and their muscles and bones start to deteriorate. To battle this degradation, crew members exercise two hours per day on the International Space Station.
The BRACE study involves male participants between the ages of 20 and 45 years with good physical and mental health. They are placed in beds tilted 6Ā° below the horizontal position. As blood flows to the head and muscle wears out from lack of use, researchers chart how their bodies react.
Researchers split the volunteers in three groups. One group cycles in bed, a second one cycles while being spun on a centrifuge, and a third control group stays in bed for the full two months with no bike exercise or centrifuge rides. The centrifuge mimics artificial gravity, acting on all organs at once. Volunteers are spun to drive blood towards their feet, where the force of gravity doubles during the ride. Scientists hope artificial gravity could be used to keep astronauts fit and healthy in space.
Now halfway through its second edition, the experiment will finish on 4 May 2024, after 95 days of intense clinical testing and monitoring. This campaign takes place at MEDES, the Institute for Space Medicine and Physiology in Toulouse, France, and is supported by the French Space Agency CNES.
The study involves 14 European and international science teams that are working to release the results from the first BRACE campaign in 2023. Researchers are assessing a wide range of changes in the cardiovascular, metabolic, musculoskeletal, neuro-sensorial, haematological, and immunological systems.
The tests will provide a better understanding of the effects of prolonged bedrest to the benefit of those in space and on Earth. Results could help design countermeasures and improve health for patients suffering from accelerated ageing due to a sedentary lifestyle.
Get ready for a magnetic overload with Science Max! This compilation is bursting with electrifying experiments and surprising science facts.
