iPhone Physics

Some of the technologies behind the iphone which involve physics have been around for sometime

The first patented wireless telephone was made in 1908 by Nathan B. Stubblefield. He applied this to "cave radio" telephones and not directly to cellular telephony as we know it today.
• The introduction of cells for mobile phone base stations, invented in 1947 by Bell Labs engineers at AT&T, was further developed by Bell Labs during the 1960s.
• Radiophones have a long and varied history going back to Reginald Fessenden's invention and shore-to-ship demonstration of radio telephony, through the Second World War with military use of radio telephony links and civil services in the 1950s, while hand-held cellular radio devices have been available since 1983.
• Along with other mobile phones the iPhone communicate through electromagnetic radio waves with a cell site base station, the antennas of which are usually mounted on a tower, pole or building.

Or the Lithium-ion polymer batteries, flash drive, sound and audio qualities just to name a few all involve physics.

I don't really understand why anyone should hate the iPhone or Apple. Seems like there's better things to worry about. Buy the iPhone (or iPod or whatever) or don't. I think many people just hate anything that achieves a large degree of popularity. Only reason I don't own an Apple myself is that they're too expensive compared to similarly capable PCs. Apple stuff is a bit pricey.

I agree but I will admit that one of the main reasons i waited a while before getting my ipod was for the same reason i've been boycotting Starbucks, I just didn’t want to be put in the same category as those yuppie fucks. Macs are awesome for editing movies, animation, music and graphic design. Pretty much a must have if your into media. Anyway I’m sure there is a good reason Apple has the majority of the market share (I think its somewhere in the 70%) where as the cheaper ones (actually the Microsoft Zune 80 G is cheaper yet only captured a bit under 3% market share) Samsung has like 11% and the rest are divided among other companies.

You forgot gravity.

Bullshit.

That was true when there were only CMYK-coded printers, when macs were the only computers to have a color-coding that would be the same "on screen" and "on print". The invention of RGB printers changed that some five years ago.

A custom-built PC beats a macintosh computer in every field, every time.
 
It's true, macs being better for media and print is an old thing that doesn't hold true anymore, PCs are on par, if not better, most of the time these days.

We went over this in a graphics design class last term, we were using both Macs and PCs in the lab. I'm partial to the G5s, personally, but they aren't actually better. I just think it's fun to use an operating system I'm not used to, that way I'm learning on multiple levels.

The only real perk of Apple computers in my opinion is the very synergistic nature of its parts. The same parts in a Mac often times go faster than they would in a PC, because they are paired with technology that makes them work well together, even better than the numbers normally imply. Theres more to computer parts than just the numbers, architecture is a huge factor, one that can't always be easily explained or predicted, and rarely ever shows up on information sheets. For example, nVidia graphics cards are known for running faster on their own brand of mobos, even when up against higher rated competitors cards.
 
Macs may not be the end-all, be-all for graphics work as they once were, but Apple still does have the majority of the graphics professional market, if I'm not mistaken. 'Course that could just be chalked up to the fact that many are just used to using Macs.

Possible. Got any proof to support this bold claim?
 
Unfortunately, there are no widely published numbers for historical market share within specific segments. It's obvious, however, that Apple maintains a significant presence in certain markets:

•Adobe reports that about half their profits come from Mac users.

Source: Apple Market Share Myth

I didn't come across any published reports, but it's pretty commonly stated that Macs dominate the graphics professional (photo editing, desktop publishing, etc.) market.

So if you're looking for 100% definitive proof, then I suppose the answer is "not really."
 
It is common knowledge among graphic designers, thats why most schools run mac labs for the art new media departments. (The other reason is because Macs offer discounts to schools on their products)

It's their perceptions, schools and other bureacracy just can;t keep up with the times. Macs aren't the graphics powerhouses they used to be.
 
The PowerPoint is done. Does anyone know of a data base which i can use to host it. I'm sure there is a Photobucket equivalent for plain data files. As for the Mac's Market Share among the artsy segmentation, I’ll try to get a reliable source out of my marketing professor tomorrow. Unfortunately I will most likely be drinking myself to oblivion because its thirsty Thursdays’ and this week was a bitch. But who knows maybe I’ll remember.

It's a watered down physics class. Not a stage for unveiling revolutionary technology. I know the iPhone is touted as being revolutionary but it doesn't really matter how inaccurate those claims are. The iPhone (like most techno-bobbles) still has enough technology in it to demonstration even intermediate level physics concepts.

Flash memory, for instance, operates by tunneling electrons through a thin oxide barrier. Electron tunneling is a quantum mechanical effect that has to do with Heisenberg's uncertainty principal.

Accelerometers are a fairly good way of demonstrating free body dynamics. The one used in the iPhone is a capacitive accelerometer. Though you could talk about other types of accelerometers. I think the ones in NASA's GRACE satellites shine a laser onto a sensor and measure the blue shift of the light.

Capacitive touch sensing uses an array of capacitors which are designed to direct a large fringe field (the stray electric field that 'fringes' out of the sides of a regular parallel plate capacitor). Your skin acts as a dielectric when it interacts with this field and increases the capacitance of the sensor.

You could also talk about the physics of cellphone radiation, ionization energy and the cancer myth. i.e.

Electromagnetic radiation can be divided into ionizing and non-ionizing radiation. Ionizing radiation can knock an electron loose, break a chemical bond, cause a DNA mutation, and cause cancer. Radiation isn't ionizing, however, until it reaches ultraviolet energies. UV causes skin cancer; X-rays and gamma rays are well-known carcinogens.

Visible light and lower-energy forms of radiation such as infrared and radio waves aren't ionizing. This is a basic property of quantum physics. Light particles, called photons, are like little balls. An X-ray is like a golf ball; it will break a window. Microwaves, the kind emitted by a cell phone, are like puff balls. You can throw a million at the window. It won't break.

The fewer people squawking about that "OMG RADIOWAVES = CANCER!" bull-shit, the better.

depends pretty heavily on what you call graphics...

yes, Mac has quite a big influence in the publisher and artist community, for no other reason than once upon a time being superior in handling that.

but you'll note that Apple uses gimped PC hardware for their graphics components for over 10 years now...
the look on MACophiles when you tell them their precious 'uber graphics card' is actually just a radeon 9700 with a solder line was priceless, especially since they paid 200 euros extra for that solder line...
 
Macs are mostly for liberal arts majors, and like most liberal arts majors: Are completely useless.

I'd say a baseless analogy like that is what's useless.

Liberal arts/studies just means basically getting general ed. out of the way. What's wrong with that? That's what I'm doing, since I haven't settled on a major yet. Makes more sense than just doing nothing until I figure out what exactly I'm going to do.

To move on to more relevant topics, Macs are pretty far from useless. I used Macs all through my childhood. Was never impressed with the PCs my friends had. Interface looked and felt clunky after being raised on Macs. Would never have even built this PC I use if it wasn't for the fact that Macs are more expensive and I didn't have the cash to spare.

"Let's not use/buy/listen to/eat something because too many other people like / are talking about it!" Yeah, that's a good line of reasoning.

I dislike hype as much as the next guy. Am I going to write something off because people can't shut up about it or an ad agency is shoving it down my throat? Well, I did that with Old Navy, but in my defense, the ads were just so damn irritatingly bad, and Old Navy doesn't make the highest quality clothing either (in my admittedly limited experience).

I'm not trying to sell people iPhones, though. Dislike it if you want. Just have some actual reasons for it.
 
Stop thinking like a Dal-ba-yob for a minute, i'm going to pass a word of advise the 3rd richest guy i ever met tough me it was in regards to a night club in Paris but im pretty drunk right now so im going to try and make an analogy: Your in a city with alot of different places to go, you walk by and notice one particular place and notice a big crowd you can’t help but stop and wonder why. You can be indie or any part of segmentation but you will find your self walking pass it at one point and time. So stop being a non conformist conformist and check the place out, you dig it that cool stay a while, if not you can always leave and find something else. Also read before posting.

i think the fact that it turns into an iBrick the moment you try to tweak anything on it is rather compelling on its own... not to mention the price of said iBrick. :roll:

rather funny to see Mac go into "vendor lock in"-mode as that's one of the many things they've always hated M$ for.

teh lulz...

I actually totally agree with that. Really, really bad decision by Apple right there. I never understood what was going through their collective minds to make an exclusive deal with AT&T in the first place.
