Alright ya noobs, I'm settling this time travel hoax once and for all. First and foremost: Time is an arbitrary notation created by man. If the whole concept were to die out, none of our maths would be any different. All you're giving meaning to is MOTION. Same with energy, there is no such thing, just different forms of motion. Kinetic energy is a pleonasm. Now back to time. How the FUCK would you translate said arbitrary time notation to a machine somehow connected to space-"time"?Pro tip: You can't.Unless you manage to install a framework in the universe with a functional API it's not happening. Yes, mass and speed (same thing) slow down motion but that's it. You can slow down your RELATIVE MOTION as opposed to others but that's not time travel. There's no destination as defined by con-artists getting grant money for fake/stupid study and spend it on booze and cocaine (like my money).Get over it. There's no such thing as fucking time travel. Niggers.
>It doesn't mean anything it's only SaturnAll the other stuff in Revelations 12 is happening (will provide pic after I post this) and it's is in the Virgo constellation near where Jupiter (the baby) will exit it. And it also does some what look like a dragon. It is also the Red Dragon>B-But it's not red it's just a filter you can make it any colorBut you can only see it with infraRED cameras.Also on 12/23/16 9 months before 9/23/17 this happend https://theintercept.com/2016/12/23/obama-allows-toothless-un-resolution-against-israeli-settlements-to-pass/also 9 months is how long Jupiter is going to be in Virgo and you know how long it takes a baby to be born... 9 monthsRevelations 12A great sign appeared in heaven: a woman clothed with the sun, with the moon under her feet and a crown of twelve stars on her head. 2 She was pregnant and cried out in pain as she was about to give birth. 3 Then another sign appeared in heaven: an enormous red dragon with seven heads and ten horns and seven crowns on its heads. 4 Its tail swept a third of the stars out of the sky and flung them to the earth. The dragon stood in front of the woman who was about to give birth, so that it might devour her child the moment he was born.More weird stuff on that date: https://www.youtube.com/watch?v=xn_l2yS6H2o
>All the other stuff in Revelations 12 is happeningNo it isn't. You're some 1900 years too late bucko.

Johns Hopkins Kimmel Cancer Center scientists report data from a new study providing evidence that random, unpredictable DNA copying "mistakes" account for nearly two-thirds of the mutations that cause cancer. Their research is grounded on a novel mathematical model based on DNA sequencing and epidemiologic data from around the world."It is well-known that we must avoid environmental factors such as smoking to decrease our risk of getting cancer. But it is not as well-known that each time a normal cell divides and copies its DNA to produce two new cells, it makes multiple mistakes," says Cristian Tomasetti, Ph.D., assistant professor of biostatistics at the Johns Hopkins Kimmel Cancer Center and the Johns Hopkins Bloomberg School of Public Health. "These copying mistakes are a potent source of cancer mutations that historically have been scientifically undervalued, and this new work provides the first estimate of the fraction of mutations caused by these mistakes.""We need to continue to encourage people to avoid environmental agents and lifestyles that increase their risk of developing cancer mutations. However, many people will still develop cancers due to these random DNA copying errors, and better methods to detect all cancers earlier, while they are still curable, are urgently needed," says Bert Vogelstein, M.D., co-director of the Ludwig Center at the Johns Hopkins Kimmel Cancer Center.Tomasetti and Vogelstein conducted the new study described in a report published March 24 in the journal Science.https://www.sciencedaily.com/releases/2017/03/170323141403.htm
New work from a team including Carnegie's Guoyin Shen and Yoshio Kono used high pressure and temperature to reveal a kind of "structural memory" in samples of the metal bismuth, a discovery with great electrical engineering potential.Bismuth is a historically interesting element for scientists, as a number of important discoveries in the metal physics world were made while studying it, including important observations about the effect of magnetic fields on electrical conductivity.Bismuth has a number of phases. A chemical phase is a distinctive configuration of the molecules that make up a substance. Water freezing into ice or boiling into steam are examples of how changes in external conditions can induce a transition from one phase to another. But for physicists and materials scientists, application of extreme pressures and temperatures can bring about a large variety of other phases. For example, under increasing pressure and temperature conditions bismuth undergoes an array of phase transitions, including eight different types of solid phases observed so far.In previous studies of bismuth, pressure-induced structural changes were not retained when the pressure was reduced. However, the research team -- which included lead author Yu Shu and colleagues Dongli Yu, Wentao Hu, Bo Xu, Julong He, and Zhongyuan Liu of Yanshan University, and Yanbin Wang of University of Chicago -- used a pathway of successive pressure and temperature conditions to create a form of bismuth that has a "structural memory" of a previous phase.https://www.sciencedaily.com/releases/2017/03/170314081621.htm

How can evolution be a fact when scientists have not observed a prehistoric crustacean evolve into a human? Isn't evolution more of a belief where you just have to have faith on the scientists hoping they're right with their hypotheses? So exactly how different is that compared to believing in God and creationism?
>>8774862there isn't fossil evidence of creationism
>>8774862>How can evolution be a factAntibiotic resistance is a direct observation of evolution This b8 threads are getting more retarded by the day
>>8774862You do always have to have faith on scientific theories (except math where knowledge is a priori and not heuristic).It's different in believing in God because scientific theories make predictions on the outcome of experiments, so it is possible to falsify them.
>>8774862>So exactly how different is that compared to believing in God and creationism?Belief is equally thoughtless, regardless of science-religion or god-religion. Science is merely one possible model for Reality. In ignorance, they reject all other theories but what their ego makes them believe.

>>8774919Yep, the same sort of fascist mentality that the scientific method was developed to combat. This is how religions are formed. We are heritics for pointing out the gaping holes of the theory and asking for supporting evidence.
Considering a Bachelor's degree in Physics because I found Physics 101 to be incredibly interesting.Is there anything for me in this field if I'm not incredibly strong at mathematics? Is strength in mathematics something that can be reasonably developed? Should I go for something else?
>>8774787What sort of work would applied physics look like, research?There's parts of math that I struggle with and parts that I find a breeze; I don't know why but radicals have always given me trouble. Actual algebra is fun.
>>8774807Understanding and applying basic formulas like ohms law or conservation of energy is incredibly easy and fun. Sitting down and doing stuff with just numbers can't hold my interest; I am an actual idiot.

I'll explain, they're crazy and exaggerated because Scientific American has been publishing this kind of pseudo-scientific social science bullshit. It's also making fun of the bullshit maneuver of using the word "Science" in the headline to make the article seem totally irrefutable.

Meet the Mequanics is good if you're into quantum information
Hi! Are you good with combinatory?We have 5 elements that cant be repeated:1, 2, 3, 4 and 5We need to know the combinations of this elements but there are 2 sets and the sets cant be repeated neither with other set with same elements. One sets has n elements and the other the rest of elements. For example, with n = 2:Set A | Set B1 2 | 3 4 5 <- VALID1 3 | 2 4 5 <- VALID1 3 | 4 2 5 <- INVALID (same combination)3 1 | 5 2 4 <- INVALID (same combination)So there is a dependency between A and B and the "inside" elements of A and B. Is this even possible to resolve with Maths?
I'm not sure i understand what you are saying but it seems to me that you just want to use the binomial coefficient, so in your case 5!/(n!(5-n)!)
If I wanted to study biochemistry, should I major in biology or chemistry?
>>8774588Biochemistry. The upside is that you can always fall back on industrial chemistry labs if the going gets rough because HR just sees "chemistry" in the major title.
>>8774588Just to be clear, biochemistry is not a mix of biology and chemistry, it's it own subject. You won't really gain much understanding of either biology or chemistry from it
The problem is that biochemistry is not available as a degree where I live and these are my closest options
>>8774722does your school have biology with a focus on cellular biology, genetics, anything like that? Because that's the closest you'll get to biochemistry probably. Chemistry is very different from biochemistry so you won't have much overlap
>>8774722Biology in my school focused on biochemistry, genetics and microbiology. I've searched for information about both degrees and I've seen that biochemistry is present in both as a subject. In the degree in biology there are subjects related to cytology and genetics while in chemistry there is organic chemistry.
Would a steel bar or a steel bar of the same size covered in rubber be more impactful/ inflict more damage?Why?
>>8774549The steel bar would. Depending on the rubber the rubber will absorb some of the impact
>>8774549Depends on what it's hitting/what velocity. The coefficient of friction from the rubber has the possibility of interacting with something more violently as it slows from ridiculously high speeds.Although if they are the same dimensions like you mention, the mass of the rubber covered will he lower, so in some applications, the extra momentum could cause more damage depending on the target.You also have to take into account what the metric of "damage" takes into account, which also coincides with what the target actually is.
