I feel like there is an expectation from society for every 18 year old to go to college immediately after high school. In my opinion, this results in millions of people being pressured to enter into a program that they are not ready for. Me, personally, I went into the wrong program at the...

Hey everyone, I need to take Gen. Chem 2, and planned on doing it over the Summer in a 6-week condensed course with another 9-week programming class. I'm not sure if this is overboard, but I feel like it should be manageable with no jobs or interns this Summer. The reason I want to take it this...

Hi I don't really know how I got to third year but I'm here and I'm a bit disappointed in the fact that I've learned stuff but at the same time feel like I haven't really learned much. I would love going through books and reading in depth about what my lecturers are teaching me, like I like...

Hi all, So the (hypothetical) question I have is about the range of the Earth's length of orbit (number of days) within the Sun's habitable zone which could sustain human life. I.e. what would the length of the shortest 'habitable' year be, and the longest (in days)? What would our living...

Course Selection is coming up next week in my school and I am still deciding between 2 slots and 3 desired classes of mine. In my school we have 8 classes all together with 4 on "A" days and 4 on "B" days. Here are my selected classes that have already been picked out: Honors Biotechnology III...

Hi guys, I really need help with deciding my courses for next year. Currently, I'm a sophomore in high school rising to a junior next year, and today, we began doing course selections for next year. Now, before I continue, I didn't just start thinking about my courses for next year today. I've...

Hi all! Now I don't know whether the question I am about to pose is something that can be answered intelligibly. Maybe it is just a case about motivation...but I am not too sure at the moment. My question is: Does mediocre performance in first and second year physics present a possible...

Hi I am applying to the universities but I think I am bit confused with something. Actually I am applying to the universities after taking a year gap. But some universities are asking me to make my decision between these two option: Mature student or high school student or gap year student...

I'm going to skip to the chase and give you the basics of my situation. I'm very weak at physics as i didn't take any high school classes (wasn't interested at the time) and also didn't finish high school due to personal reasons. I'm fairly good at algebra, some calculus but could use a lot...

Homework Statement Emily's brother, Jack, is now 105cm tall, having grown by one sixth of his height a year ago. How tall was Jack one year ago? Homework Equations Now my teacher told me to do this: x = 105 - (105/7) x = 105 - 15 x = 90 cm The Attempt at a Solution So 90cm is the answer...

I am a senior in high school who is anxious to begin my physics major. Next year, I will likely attend UC Berkeley or UT Austin. I have general question, but if someone has information particular to these schools, that would be appreciated too. What does the course load for a first year physics...

Homework Statement A space traveller lands on a small planet whose circumference is 12,500 km. He releases a hammer and a table tennis ball simultaneously from rest and from a height of 1.6 m, timing their fall to take 0.66 s. Determine the density of the planet. What can you conclude about its...

Last year I tried Single Variable Calculus (very good course) and look some videos of Multivariable Calculus on MITOCW and I cover almost all the material. So, when I took that course I realized I want to learn about mathematics. I want to be a PhD physicist (and I know that it cover a lot of...

Homework Statement How would you calculate the length of a year in Earth years on a hypothetical planet? (given the mass + radius of the planet) I understand Kelper's law is used somehow, but is orbital velocity needed?

Homework Statement A tree loses water to the air by the process of transpiration at the rate of 110 g/h. This water is replaced by the upward flow of sap through vessels in the trunk. If the trunk contains 1900 vessels, each 100 μm in diameter, what is the upward speed of the sap in each...

Hello everyone. I am a second year physics student at a large research university in Ontario. The math courses required for my degree are Calc 1,2,3 and vector calc, linear algebra, ODEs and PDEs. I have taken linear algebra, calc 1-2 and stats (not required) and am currently taking calc 3, ODEs...

hello all, I just wanted to check my worded interpretation of this otherwise messy result is ok:

Homework Statement Planets A and B are 10 light years apart in the reference frame of planet A. A deep-space probe is launched from A, and 5 years later (in reference frame A) a similar probe is launched from B. Does a reference frame exist in which these two events (a) are simultaneous and (b)...

It's the middle of the semester of my first year and I'm finding this math course extremely difficult. The course is essentially teaching real analysis and they labeled the course honors calculus. I am finding the professor is not teaching the material well which made me find some supplementary...

http://www.sciencedaily.com/releases/2015/10/151006192107.htm A new study shows that iron-bearing rocks that formed at the ocean floor 3.2 billion years ago carry unmistakable evidence of oxygen. The only logical source for that oxygen is the earliest known example of photosynthesis by living...

I'm looking for some appropriate 1st year, or possibly 2nd year, level grad texts on galaxies and cosmology. The grad course at my university requires Cosmological Physics by Peacock and Galaxy Formation by Longair. I've noticed many old cosmology course websites require Weinberg or Dodelson or...

I'm having trouble trying to find part-time work to pay tuition & books at my CC I currently attend. Here are the places I've been applying / going to apply: - Best Buy / Geek Squad (also 3 local locations) - Staples Retail (3 local locations in my area) - Lytespeed Computers - NFP...

I'm helping my nephew in school who really wants to be part of robotics class. I don't know why. He is a year under being considered, and next year, in order to "apply" he needs to make a robot, and film a documentary on how, why, he built it, and why he should be accepted. Electronics and...

I'm entering my 3rd year, for a bachelors degree in Physics. I messed up in the first year and now I'm trying to catch up. Can I get a place in a university for a doctorate or MA afterwards?? Even if my grades are really good in each subject/course? I'm getting worried! Thanks.

Hey guys, From the title you probably get the idea about my question as I am so confused. How come a left click of a laptom Touchpad started to work normally after having a problem with it for more than a year? I really hope it is not a short therm thing, as I have no logical explanation for...

Hello, 1. Could anyone tell me if taking these classes and this many classes is an overload for a Senior Year in Mechanical Engineering? (Fall 2015 Semester) -Fatigue in Mechanical Design - elective - Manufacturing and Design Concentration - med/hard -CAD - elective - Manufacturing and Design...

Hello, I’m doing my first year of bachelor degree in physics in Italy and I would really like to get some research experience before my third year. Do you know any (international) summer research opportunity for a physics student who completed his first or second year of studies? I would be ok...

I am registered for Thermal Physics for this year (my junior year). The online curriculum advises physics majors to take it fall of their senior year. (The class isn't offered in the spring.) I am taking 3 other physics classes as well. I felt inclined to take thermal this fall because I wanted...

I've just completed my degree in maths and physics and am going for a maths masters the following year. Am I likely to loose any sharpness in this time? Without really knowing what modules I'll be doing and even if I did, each lecturer seems to approach a specification/ prioritise certain bits...

Should I opt to do research which would be very time consuming or focus primarily on my remaining upper level this year and get As? Thinking to do research after I graduate next Summer. I've only had 1 "REU" so far.

Hi, Just wondering: The lunar orbit around the Earth is tilted 5.1 degree with respect to the Earth's orbit around the sun (as described in the video), so only at 2 times during the year the Earth is aligned with the sun such that lunar eclipses can happen IF the moon is behind the Earth...

I am looking for any ideas for my final year project for my electronics engineering technology course... Please let me know some of your ideas

I've noticed that Harvard Extension and other colleges seem to only offer one year of "physics" courses in their course offering books. After the first year, what is a logical next step for someone wanting to learn more? Favorite physics topic is electricity, all applications of it.

So I got killed this past year in physics. Combined with the fact that I slacked off a lot in first year, I have an awful GPA. It's currently sitting at 1.66 ( out of 4.3) I need ~2.0 to get into honors physics. I'm guessing the possibility of grad school is out the window. I've been studying...

Hello everybody, Like you, I love physics and would love to obtain at least a B.sc in Physics, but I am in a sort of a dilemma. Should I go to Leipzig, where they have an English taught bachelor or should I spend a year studying German in order to take a DSH exam and then attend a German...

Hello, I'm currently a philosophy major and I'm going to start my sophomore year this fall, but I've considered changing my major to astronomy. The problem with this is that I've always wanted to graduate in just 4 years, and the only way this could happen is if I filled up the next two summers...

For my year 12 physics EEI (extended experimental investigation) i need to develop some sort of experiment with variables i can change to retrieve data from. I have a basic cathode ray tube from a few months ago much like the one in this video: . Does anyone have any idea of what variables i...

Ideally I'd like to apply to graduate school for physics (leaning towards Astrophysics or Condensed matter); however, I don't think my course work or research is sufficient. I'm already using an extra year to complete the degree (I changed to physics the end of my Sophomore year) and wouldn't...

My friend is doing this for his final year design project and has hit a brickwall in terms of understand the actual process. Any help would be appreciated!

Background: I am a non-traditional student currently enrolled in a large research-centric university planning on majoring in physics. Graduated H.S. in 2009. Spent 5 years in the military working in a field wholly unrelated to any of my studies(current or planned) The situation: I see a lot of...

OK, either I'm looking at this the wrong way, or this is way above what a 10 year old should be. Following are 2 equations containing A, B and C. A solution must be found that solves both equations, i.e. A, B and C are the same in each formula. Also, A, B and C must be whole numbers; C+2A=3B+2...

I signed up for my first semester classes and I'm in the first calculus based physics class. I took calculus in high school, but my physics classes weren't all that intensive in my opinion. Well, I guess that's what you get when your teacher has to teach 8 classes and work as a lab technician in...

I think first and second years of engineering are same for all branches worldwide. Is the syllabus different in other countries or same for 1st and 2nd years? Well I haven't gone to a university yet but do the university people tell us which book to buy or we have to decide on our own? It will...

So, I go to a relatively small school and don't have all that many options, but I'd like to ask about the couple I do have. I am going into my forth year, but because of the rotational schedule of the math and physics departments I took all the available forth year courses in the previous year...
