PREPARE is an acronym for the European Union's Platform for European Preparedness Against (Re-)emerging Epidemics. The coordinator is professor Herman Goossens of the University of Antwerp. It was activated on 31 December 2019 in response to coronavirus disease 2019 (COVID-19) and as of February 2020 was operating in outbreak response mode 2 (mobilisation), the second of three modes.
I've been given Gravitational Waves: Theory and Experiments Volume I to read for a project. The problem is, I haven't learned General Relativity to a high enough level and the book is proving very difficult for me. The book dives straight into linearised gravity in the first chapter, and the...
After reading some introudction of quantum states (pure and mixed), I know that states produced statistically are called mixed state. My question is: since there always exists stochastic process, so in practical system, how can we produce "pure" state?
Homework Statement
In 50mL flask prepare sol 50 miM in SDS and 30 miM in Na C l"
MW of SDS = 288.38g/mol
MW of NaCl=58.44 g/mol

The Attempt at a Solution
I think aqueous means I should dissolve it in water. So SDS in water, then NaCl in water...and then combine it...
The title of this may be a little confusing.
My delema is this:
I am a physics undergrad with only one more semester left to go. I am also a co-op at a really great little company that designs and produces waveguide optical components, sensors, microfluidics, and spectrometers - really...
I don't know if its just me, but I think the wording of the question is weird and I'm not really understanding what it is saying. I have stared at this problem for many hours and have even went to the teacher to try to clarify. The teacher provide us with the actual work on how to calculate...
I am a first year physics student going into my second semester. Plan is to take 3 semesters of calc. and differential equations. I was going to take linear algebra this up coming semester but it was canceled dew to lack of interest can anyone recommend some other important maths to take?
Soon I will be applying to graduate schools. In general, my interests lie in the domain of cosmology/astrophysics--don't know if theoretical or experimental, but I probably don't have the mathematical background for theoretical yet. However, most physics graduate programs do not start until...
Hello everybody.
I would like to ask anyone who have taken graduate electrodynamics with jackson.
What do you think is the best way to prepare yourself to graduate electromagnetism by Jackson, if only electromagnetism by Griffith is covered during undergrad.
In particular, what...
Since I am about to start college, and I already know I want to go to grad school for nanotechnology, and I was wondering which major(s) I should take in college. I want to use nanoscience to fight diseases and cancers, and hopefully to stop genetic disorders. Initially I wanted to go into...
Hello,
I am applying for some jobs that have pre-interview tests. Here is one description:
This is for a finance job, and I am an electrical engineering major with a pretty high gpa. So I obviously have a solid math background, but what should I expect from these kinds of tests?
How...
I'm starting my undergrad in electrical engineering at McGill University this fall, and while I know that it's still years ahead of me, I want to know how I can best secure my chances into whatever grad school I want down the road.
I plan on doing their honours EE course, as well as a minor...
I want to get a book on inequalities to help prepare for the Putnam exam. Its common for me to spend about half an hour getting frustrated on a practice problem and then find that the only way to do the problem is with an inequality that I have never heard of. Does anyone have any...
I was told by the academic adviser at the University where I will be transferring in the near future that the hardest courses are the two Modern Physics courses, along with E&M, too. What book should I read to get a headstart? She also said that the courses will be a lot faster-paced than at the...
Ok, here we go.
The question asks,
for matrix A =
1 1 3
3 0 1
2 2 6
, find a vector b such that Ax(x is a vector) = b has no solution.
I found the rref(a) =
1 0 1/3
0 1 8/3
0 0 0
Now to, answer the question,
I gues the equation has no solution if one of the rows...
how would you prepare a 100ml of a 0.1M sodium phosphate buffer containing 0.5M NaCl,pH7.6 using henderson hasselbach equation??what chemicals would you use n how would you go about it
Homework Statement
How would you prepare a 500 ml lab stock of 20% (w/v) SDS
That is all that is stated in the problem.
Homework Equations
I'm assuming for w/v the volume would be 0.5L but the weight I'm not sure.
The Attempt at a Solution
0.5L x .20 = .1g SDS / .5 L .. is...
okay, i already take an intro to proofs class. did average in it. I'm taken real analysis in the spring, but as a degree audit course. the semester following my spring semester , I am take real analysis for a grade.whats the best way to prepare for real analysis?
Kia has decided to wed, and now all i have to do is buy a royal blue suit with all the trimmings, i mean royal blue is that not a bit iffy?
And i have to make a speech, ok for most guys, but i hate gatherings, i will do my best but i am sure i will cock it up.
I want this day to be a day to...
I'm interested in participating in some high level physics contests in Canada, such as the Sir Isaac Newton (Waterloo) and Canadian Association of Physics High School Prize exam.
I don’t have much experience with contests and stuff, so could you please guide me on to the best way to prepare...
Hello,
I am very interested in learning physics, and I think that it is one subject that I actually find interesting in school. I have already completed a year of physics (grade 11), and now I'm in my second year of physics (grade 12).
I am wondering, is it enough to just read my teacher's...
GREs! Verbal: How to prepare??
I know they say that having a good vocabulary is the key to success in the GRE verbal section. But I have memorized 3000+ words from Barrons's and it didn't raise my score much. Last weekend when I took the test, I rarely encountered the words that I had studied...
Hello all,
I am taking a linear algebra course at my university this fall. This course is used as a transition to more proof-orientated courses. From what I hear, this course is one where students generally do poorly if they lack the ability to construct proofs. I don't have much experience...

I have been invited to a math contest that will take place a week from now. Its questions are all essay response (proofs and numerical answers) and it is difficult. I have never written a contest in this format before. How do I prepare for it? And how can I ensure that I am lucid as Euclid on...
I'm doing a review in calc I to prepare for calc II. I'm now applications of derivatives (optimization). Okay so when I have the function I need to optimize, I need to take the derivative and find the critical point of the first derivative. But sometimes there's more than one critical point. Is...
I'm planning on entering graduate school to obtain a PhD in elementary particle physics. I graduated in 1996 with a physics major. I have NOT worked in this field since that time - I now have a J.D. instead.
I need to refresh my math and physics skills to take the GRE. I would imagine a...
So i have a midterm tomorrow in E&M and I'm not well prepared at all. The whole class is pretty much already prepared to fail... so I'm not alone in that at least. Basically, i have one more day (tomorrow) to study, so i best make the best of it. We get to bring index card "cheat sheets" that...

There is talk of a record snow fall down to the valley floor, this weekend. Some meteorologists are talking about the possibility of very cold temps, down in the teens, and snow conditions not seen since the early 50s. One model would leave us with about 50" of snow on the ground where we live...
I graduated with a BS in physics last spring, and just finished the whole grad school application process. I now have from Dec. '04 - Sept. '05 to do what I want with my life, and I was thinking about how I should prepare myself to begin graduate school. I would particularly like to hear from...
Hi!
