I used Serway Physics for Scientists and Engineers 6th edition for my undergrad degree. We used PhysicsNow, an integrated interactive tool with the Serway textbook. I found a copy that has an un-used code for PhysicsNow, but it looks like PhysicsNow no longer exists. Anyone here familiar with...
Hi all,
I suspect some of the same, blackmail emails I've received may be the result if my carelessness in not clearing , cleaning/wiping out the metadata in some of the links, pics I've posted. I doubt PF is part of the problem, but likely others are.
Is there some good freeware to wipe it...
hi all! I'm a first-year second-semester physics major, problem is I'm very weak at math, often not getting questions right just because I get stuck with the mathematics part. this affects me in both mechanics and electricity
what are the most important math subject and tools needed for physics...
Suppose that I can generate the result of a function ## c_{x,y}=f(x,y)## by a method not involving the function ##f##. I need to find ##f(x,y)## now. The expression of ##f(x,y)## is expected to contain basic algebra operation (+-*/), power, absolute value and factorial.
I have tried to find it...
Is any tool available for a person to use instead of putting their weak finger nail into the groove of one of the functions of a swiss army knife or victorinox knife in order to open that function? Some of our nails are just not tough enough to put into those grooves to pull the function out...
I was looking through my arrow heads so I could add another row on this board: https://www.physicsforums.com/attachments/img_3670-jpg.290343/
and found this tool?:
I'm not sure what it was used for, maybe for scraping? It was found with the arrowheads in Arkansas.
Also found there was this...
No, this isn't a homework question. I'm genuinely curious;
If I were to magically teleport and happenstance with a shovel and survive the harsh climate, could I use said shovel? Maybe hand drills? I would assume the shovel would be a class one lever, and thus the moon's lower gravity would...
The first career that I tried to have was as a mechanical engineer. I majored in mechanical engineering at a university, but I failed out of the university.
I've always been curious as to exactly what most mechanical engineers do most of the time. I imagine that the vast majority of the...
I finally decided to learn how to program in Python. The basic syntax seems easy enough, but I have a few questions:
There is a dizzying array of editors and IDE's out there. What is a good option to get started?
I've never programmed (or done anything technical) on Windows. Is there any...
I am a mechanical engineering student and I know that our school will use ANSYS as simulation tools in the fall semester. And when I talk with one engineer, I know that they will use different kinds of ANSYS tools for the same project. The engineer uses ANSYS’s tools: Mechanical, Fluent, Maxwell...
I've replaced the charger for my DeWalt tools several times, and now I may have to go out and get a fourth one.
One of them flashes a fault warning (steady slow flash), the other two do not light up at all.
Now, I do not take care of my tools. All three of these chargers may have been exposed...
Hello Colleagues,
I have a project for medical application. It has a cutting part for precise incisions. It should have excellent notch tensile strength and resistance to pitting corrosion. Obviousely this should be surgical steel or titanium. What would you take?
I remember reading on a blog or a news article on the internet once that sometimes counterfeiters have made fake silver coins and silver bars out of molybdenum. Silver is worth far more than molybdenum. Counterfeiters made fake silver out of molybdenum because they could acquire the molybdenum...
Wax moth larvae can consume and degrade polyethylene at an impressive rate
Researchers in Spain and England recently found that the larvae of the greater wax moth can efficiently degrade polyethylene, which accounts for 40 percent of plastics. The team left 100 wax worms on a commercial...
I have been working on some projects, I build a glass grinder, faceter with a 120v induction AC motor.
Its not possible to effectively change the speeds with electronic controls being a single phase motor.
It is using belts and pulleys for now.
So I am wanting to build several tools, rock...
In the IB diploma program, they ask for a "Mathematical Exploration", where I have to deal with a topic with mathematical tools.
For example:
How to get the perfect exit of Gymnastics Bars?
In "exploration" you have to see the measurements, the angles, velocity trajectories, mathematical tools...
I want to know what mathematical tools I would use in the event that we have the right technology. So far I have only calculated the distance to Alpha Centauri using parallax.
I need any other tool: hypothetical speeds of ships, trigonometry, vectors, trajectories, any tool that is necessary...
In case the orientation of a primitive cell is not what I want, is there tools to do a user-supplied 3D rotation to bring the primitive cell to the preferential orientation and output the new coordinates? Thanks,
Hi everyone.
Looking to get back into offering private tutoring in physics. (Mod note: changed "tuition" to "tutoring" here and in the thread title.)
I used to carry a few textbooks with me and my paper notes with lots of printed exam papers for student to try.
I am looking to go paperless...

Hello,
I have to hold a short course on applied mechanics and mechanical vibrations and I would like to develop a tool similar to the one shown in the linked webinar below (min 27.43):

I need the math tools to understand and analyze sequences and their convergence. I know for example that the fibonacci series can be rewritten such that we can calculate for example nr 153 without knowledge of previous numbers. What math subjects is needed to take care of more complicated...
What kind of collaboration tools do you guys use in Physics?
Let's say you need to work in a group for a class. How do you collaborate with the other members of the group? Do you use a special messaging app? Github? Trello?
Do you have a home lab? What does your lab consist of?
My lab mostly consists of electronics tools like an oscilloscope, function generator, various power supplies, meters, and so forth.
Maybe it is not that specific to social studies when one is talking about document computing tools (which I refer to content-related tools here, e.g. Charting, Visualising, Flowcharting, and Infographing tools, etc), but I really am curious about what specific tools are social studies...
I love measuring and quantifying the world. I'm curious if I'm missing any good, essential tools. I'm also curious of some good, affordable fill-ins for some measurement capabilities that I may be missing.
I currently have:
Laser Distance Measure
Radar gun
Scales
IR Temp Sensor

Homework Statement
Car mechanics use compressed air tools to open bolts. Instead of using an air compressor one can also use a tank of pressurized air. There is an air tank with a volume of 50 L to work with. The pressure of the tank is 50 bars when it is stored indoors at 20 °C. The bolt...
Why Graphing Tools doesn't represent hole in a graph of a function. A Hole at a point in a graph is point where function is not defined.Suppose there is a function
##\frac{x}{\root{x-1}-1}##
Its should be like this
But online tools and even my android graphing tool app shows graph like this...
ello all,
This is largely a repost of something I posted on r/math, but didn't seem to find any luck there with two of my questions, so I'm asking it again here with the hopes that someone here can answer my questions. Thanks!
I'm studying for a final in geometry, and I know I'm going to get a...
Hello guys,
Haven't posted in a long while, but I need some advice. Not sure this is the proper subforum, but here it goes:

I need certain tools to do my job, but my boss want's me to use bovine manure tools that don't work well. I.e. it will take huge amounts (weeks) of both my and my teams time. While the right tools will cost a few hundred dollars and will be working within a week.
I've had this problem...

I know physicists use measurement tools to measure things from speed to capacitance, but a lot of people tell me that physicists have hands on work.....where is this hands-on work? Besides doing the math and measuring data in experiments, what do physicists do that can be considered hands-on work?

dX2/dt = f(X1,X2, u2, p2)
where X1,X2 are state variables, u1,u2...
