But how can an operator be added to 1, and then multiplied. Let's take this case, d(x^2)/dx + x^2 = 35 (in this case, x is 5) (d/dx + 1)x^2 = 35 d/dx + 1 = 35/x^2 d/dx + 1 = 7/5 d/dx = 2/5 How can d/dx just simply be "given" a value?

Hi all, I was relatively comfortable with Leibniz's notation of dy, dx as representing infinitesimally small values of change in y and x, however I was watching a Math lecture yesterday where I saw something I was simply unable to conceptualise. I've always seen the d as an operator, that...

Yes at some universities I have seen courses specifically on Machine logic, but those aren't my top choice Universities. Commerce and Management seem quite useful for employment and career progression, but Science seems more useful for analysing and solving problems like you said (different...

Hi all! I am currently trying to choose a degree to conjoint with my Engineering Degree. I was hoping I could call upon your infinite wisdom to assist me. My options are as follows: Commerce Science Business Management Information Technology No Conjoint I'm leaning on the side of...

What's being measured is the input energy via. Voltmeter + Ammeter, and the output energy as temperature of the liquid solution and mass of liquid lost. The enthalpies of formation of species are not considered and yet there still is an overall rise in energy. Any ideas?

Hi, I was wondering, for a process that produces a large amount of heat, are there any efficient systems out there to transform this into different types of energy (chemical potential, electrical, mechanical, etc) with a high efficiency (80-90%+) Thanks.

Hi all, I've been doing some experimentation with the electrolysis of water, however I can't seem to be able to get clear gaseous results? I have two electrodes stuck into water, with a 240DC, 3A Current passing through it. I have a 0.5Molar K2CO3 solution. When I turn on the power...

Ok, so in any case that light is emitted, it is also a case in which heat is being emitted? Is it possible to know the temperature of a compound based on the wavelength/intensity of the light?

Don't quote me on this, as it is just my own ideas, but yes I think it is simply a case of two opposing forces acting in different directions, and one being simply stronger than another. It's like two vehicles pulling the same load in opposite directions, except one vehicle is a truck, and the...

Nitrogen is only a good inert gas for medium to low temperature processes. It's almost like a "fake" inert gas, because it only acts like an inert gas because it has a triple bond in its structure which is very hard to break, so it will not react in lower temperatures. At around 1500C it will...

Hi there, I was just wondering about this point, why do some chemical reactions produce bright light (and even sound) whilst others do not? For example: in the rapid oxidation of Magnesium in air after given the necessary activation energy, a bright white light is emitted. However, in many...

Hi there, As we know, many innovations and designs in science are based off the natural world. I was wondering if it would be possible to create an efficient process of energy transfer similar to how living organisms work, with their use of Enzymes, ATP, etc for relatively efficient energy...

Possible Exothermic Reactions? Hi there, I've been doing some experimentation lately, but have come to a wall in terms of ideas for a possible explanation. In a solution of only water and 0.5Mol Potassium Carbonate Electrolyte, a high electrical charge is passed through a tungsten...
