From my limited mathematical perspective it seems that 'mass' should just be another dimension or variable property associated with wave quanta. You know, a photon has zero mass, an electron has 9.11 × 10-31 kg of mass, a proton 1.6726 × 10−27 kg, etc.

Is there any real expiremental evidence that subatomic particles actually 'occupy' space, i.e. have length, radii, density or any of these other properties we consider of objects 'occupying space' at a macroscopic level.

If the answer is no, is the occupation of space just an illusion used to facilite understanding and interpretation of macroscopic interactions, or do we view the combined wave interactions of subatomic particles into atoms as an impenetrable occupation of space, though the atomic constituents are 'spaceless'?

Philisophically I'm fine in any direction, it's just a question I've never seen explicitly asked and answered anywhere.

Most astronomers always jump to conclusion about new discoveries.
they see something new in the sky such as a quaser blowing up..lol
or maybe that giant storm on jupiter that's been raging for thousands of years suddenly stop
or maybe they see the same star appear in two different places due to strong gravitational fields from an object that they cannot see.
my opinion is much like sherlock holmes..

"It's a capital mistake to theorize before you have all the evidence."

and astronomers do not have all the evidennce..

1.) Solve the inequality and write the solution in interval notation:
/3x + 1/>10 ...(the absolute of 3x plus 1 than greater than or equal to 10)
2.) Factor the expressions 15b2 + 4b - 4 and x64 - y64..using any method
3.) Use the factor theorem to decide wheather x-5 is a factor of P(x) = x3 - 3x2 - 8x - 10
4.)Find the domain and range of f (x) = x + 2/ x..and how you would graph that..
THANK YOU...CORRECT ANSWERS= 10PTS!

Say that someone died from cancer or lung disease or any other non-violent means. One that did not overtly damage the body. Freeze them up...put them in a craft where decomposition was eliminated...and send them away....into space...with no expectation of return. Your thoughts?

Hello,

I have heard that cranial features become exagerrated as we age. After puberty, some say that skulls elongate, foreheads broaden, but I was just wondering if there was a professional opinion on this that could help out.

Specically, what kind of changes occur as the result of aging and maturation, and when do these changes begin to occur? (ie: do skulls begin to lengthen, enlarge in the 20s, 30s...?)

I am in my early 20s and would be very interested to know how, or even if, my skull will change in the coming years.

Thank you!

2/1(3x + 2y) = 6 2 in 3x/2 cancels

3x + 2y = 6
