A tool is an object that can extend an individual's ability to modify features of the surrounding environment. Although many animals use simple tools, only human beings, whose use of stone tools dates back hundreds of millennia, have been observed using tools to make other tools. Early tools, made of such materials as stone, bone, and wood, were used for preparation of food, hunting, manufacture of weapons, and working of materials to produce clothing and useful artifacts. The development of metalworking made additional types of tools possible. Harnessing energy sources such as animal power, wind, or steam, allowed increasingly complex tools to produce an even larger range of items, with the Industrial Revolution marking an marked inflection point in the use of tools. The introduction of automation allowed tools to operate with minimal human supervision, further increasing the productivity of human labor.
Hey everyone-
Does anyone have any idea what kind of software/computer languages/tools a control systems engineer would use on a daily basis?
I know 'control systems engineer' is a vague title- I'm looking specifically at like aircraft flight control systems (networks of mechanical and...
Hello,
I have been trying to help a friend of mine some descriptive geometry like orthographic projection of planes etc . . . I was wondering if someone can recommend a simple software that has the very basic construction tools like a ruler, compass, protractor etc so as to record some of the...
I have worked with softwares that help me simulate circuits (Hpice, Proteus, MultiSim), but is there a software that helps me simulate devices right from the level of the atom?

I am currently reading the book on quantum mechanics by N.Zettili. It's really a good book but has a lot of mathematical stuff which I am not able to absorb. There's a whole chapter on mathematical tools but it is difficult to.understand. Can anyone suggest me book or text on mathematics as...
Hi all,
I want to learn tools like MAXWELL 2d 3d , MAGNET, FLUX etc.
I want to know if I'll need to know CAD and FEM Analysis to learn the above mentioned tools.
Thankyou,

is there "cheap" / high productivity way to measure quality of hand tools?
I see online a common complaint that widely available tools have become low quality due to offshore outsourcing, cost cutting, corrupt/lying mislabeling of alloys used etc. Conversely, tools of "proven" brands that have...
So, its a long post and I feel I've been pushing this thing further and further without considering it properly.

I can not find any useful online tool that solves you a system of equations using Gaussian elimination and LU decomposition. So just a system like:
-3X+4X+9X+4x=-2
9X+2X+1X-5X=2
etc. Just about 4 lines.
several lines. So basically an online tool where you can just plug in the...
Do quantum field have ontological reality or are they only mathematical calculational tools just like virtual particles? What's the mainstream consensus?
Folks,
I am reading some literature on QM. From what I understand QM can be used to great accuracy to predict the outcome of experiments and help to improve technology etc etc without having to worry to much about what it means i.e. the interpretations etc, i.e. the shut up and calculate...
Hi. I am aware that Fortran, Mathlab and Mathematica are used somewhat extensively in physics. Due to some technical and administrative problems I was unable to return to the labs to learn any of the three stated above during the long break. I only have limited access and would have to use the...
Hi all! This forum has been very helpful to me in the past, so I thought I would post this question here.
I have what are basically machine tools that I am trying to examine in the SEM (I also use profilometry to gauge surface roughness). After use, the tools have residual Aluminum on...
Homework Statement
Solving y^4+4y-69, I got the following:
By manually plugging in, I found that y= -3 and y=2.76.
However, I would like to ask you if there are other good, efficient ways to find solutions?

The Attempt at a Solution
This refers to nanotechnology. But I'm confused when they state the scale of the tool and the scale of the object. Therefore, would the...
hello everybody, I am going into my 3rd year as an EE major, usually between semesters ill either prep or try to learn more tools for my tool box. my question is this: are there any tools (languages, certifications, subjects, etc.) that would "really" aid me when i enter the workforce...
Basically I have the following system:
ac = A
ad + bc = B
bd = C

I'm trying to study wear patterns of tools in a manufacturing process. My plan of attack is the following:
1) pre-image the tool in the SEM
2) use the tool to machine a superabrasive material
3) remove the excess Aluminum from the tool that accumulates during the machining process using NaOH...

Other valuable insights into tooling include the following:
How little we men know about ourselves.
We all know that a lot of machinery goes into study the set of natural integers such as algebraic number theory and analytical number theory. Why are the natural integers so special? What other mathematical objects involve so much attention in terms of machinery used to study them?
TOOLS? For measuring surface friction?
Are there any good tools out there for measuring the friction of a surface such as a road or ice or other surfaces?

I'm currently taking calculus ("differential calculus of several variables") and I really dislike math (even though I used to like math), but it's required for my major (comp sci). My teacher can't draw and does not show us graphics of 3-D graphs and functions, so I have a hard time 'seeing'...
