I need to determine an equation that models tidal patterns. High tide is at 12:00am Low Tide 6:10pm High tide returns at 12:24pm High tide is 5.4m and low tide is .1m Therefore the amplitude is (5.4-0.1)/2 = 2.65 The mean value is 2.65+0.1=2.75 Therefore y=2.65cos(Bx+c)+2.75 Im yet...

Homework Statement A gardener has 12 tulip bulbs to plant in a box (4 columns by 3 rows). There are 4 white, 4 red and 4 yellow bulbs, and exactly one bulb is planted in each small square. a. How many different color patterns are possible? b. How many of these patterns have each row...

Hello everyone. Very nice forum you have here. I came here to ask if someone can give me a few pointers on Physics. I am totally lost here. I found this page http://www.ictshirts.com/t-shirt/122/quantum-physics-electron-double-slit.htm and they talk about electrons, double slit, interface...

Dear All, Could you give me examples of conjectures based on perceived patterns but proved to be wrong? Fermat numbers, with Fermat's conjecture that all Fermat numbers are primes, would be one example that I know of. I would appreciate elementary examples which are easy to understand. The...

(This is about SR. Really.) While learning sailing the other day, I was told I was understeering when tacking. Here's my problem: 1] "Close haul" is a Point-of-Sail less than ~30 degrees (or so) from head-to-wind. (i.e. if the wind is coming an angle less than 30 degrees off the bow, you...

Could anybody say please, what change might occur in our current weather conditions, if the Earth rotated vertically, instead of the current angle of 22 1/2 degrees.

I'm experimenting with zeta function right now, and I assume there must be some kind of patter in zetas of consecutive (even) numbers. For example when we do, \zeta(2)=\pi^2 /6 \zeta(4)=\pi^4/90 \zeta(6)=\pi^6/945 \zeta(8)=\pi^8/9450 However, \zeta(12)=691\pi^{12}/638512875 So, Can...

Hiya, so, design patterns: worth taking a look into it, or a dead-end street? I thought it sounded very interesting, but then I read this on Wikipedia: Any thoughts from people with more expertise?

Help! Factoring Patterns ok i need help asap! test tomarrow and have no clue what to do! :bugeye: i need someone to help me understand the steps! ex problem 10x[squared]+6x-28 answer 2(5x-7)(x+2) what i need to know is what steps do i take to get the answer?

Hi, I just wondered what patterns are known about the prime numbers ? cheers roger

ok, so for an isotropic antennae the radiation pattern is uniform in all directions (i.e. a sphere). So for this pattern, is there a formula for determining the diameter of the sphere, or is such a measurement meaningless? also, suppose a ground-plane an arbitrary height below the antennae...

Suppose you discover a pattern involving prime numbers, or some other pattern in numbers that may be important to some mathematicians, but the pattern is so simple and straight forward that it does not really rate a whole paper to be written about it. Where do you submit simple patterns for...

I have no clue what pattern in these sequences have (help): (i)5,4,9,13,22 (ii)1,2,2,4,8 (iii)1,8,27,64 and can someone give me some advice how to notice patterns.

Hello, I've been searching all over the internet and looking through my ecology book to help me write a paper on ecological patterns. However, I'm not sure what an ecological pattern is. Does anyone have any examples I can work off of? Thanks, Yorkie6

When do single slit diffraction patterns occur (i.e. when is the formula sin(theta)=(lamda)/b applicable)? Is it only when the light gets put through a lens and focused on a single point at different angles, or is it generally. My textbook derives it for when the light is focussed, but my...

I have a tricky question here... Please just feed in any comments, anything you can spot that I can't I have been asked to compare the formulae of Sygma (k=1 until n value) of k, Sygma (k=1 until n value) of k(k+1) and Sygma (k=1 until n value) of k(k+1)(k+2)? Hence comparing these...

I have a problem in which there are two radio broadcasting towers places a given distance apart (136 m). Each tower is broadcasting at the same frequency as the other one, but the frequency (or rather the wavelength is what I am concerned about) can be adjusted to alter the interference at a...

I was reading through various books about black holes, time warps, and multiple dimensions, and now I am simply asking for clarification on a few things, and previous discoveries on something I noticed while looking at geometric patterns via different dimensions. Last part first. Let me...

I have a number pattern I need help with... can someone complete the pattern and explain the process: 700,500; 600,200; 499,900; __________; ___________; _____________ Pattern explain:________________________________________________________...

Hi hoping someone can help me with this problem. If I block plane monochromatic light (wavelength lambda) with a circular disc of radius r, and then look at the diffraction pattern on a screen placed a distance x behind the disc, I get a bright spot in the centre of the shadow. All well and...

Okay, I'm sure that most of you are familiar with Spirograph. You could make all kinds of neat patterns with it. Well, the other day I was doing some playing around with my ray-tracer (POV-Ray), and after a while I came up with something that reminded me of one of those Spirogragh drawings...

Is it true that firing SINGLE electrons or photons at a double slit over a time interval will create diffraction patterns? And does anyone know of articles where particles can create diffraction patterns.

I know that the game notpr0n has been posted here before, and I'm on stage 3 of level 79. I need to solve 2 number patterns: 6, 5, 9, 10, 4, ?, 5 and 501, 10, 999, 4, 1, ?, 11, 500 I need to fill in the question marks :smile:

Take a two-slit diffraction experiment. From what I've read or gathered, it is supposed to be caused by the geometry of the setup, and the frequency of the light (maybe a few more things). But, it is talked about in terms of the geometry, and no cause attributed to interactions between the...

I've been trying to figure out this number pattern in the image below...Can anyone help please? My head is spinning :smile: Thanks :)

I'm reading through the book "Linear Algebra", by Jim Hefferon (which you can download for free!). In section I.3, he describes that the pattern of solutions for a system of linear equations: "They have a vector that is a particular solution of the system added to an unrestrictred combination...

I understand that the consensus of opinion regards photons as particles. My difficulty is in picturing how particles can produce interference patterns, even if only one photon is involved? In the double slit experiment for instance?

The last few days have been very cold and when I come back to my car, water has condensated (to solid phase) in the windows. I have noted that the ice seems to form in lines that cross each other (forming seemingly random patterns made of almost perfectly straight lines) Of course there is...

The universe must either have: A start and an end. A start and no end. No start and an end. No start and no end Or a combination thereof. I believe there are limits to complexity, I believe complexity to be a product of thought, if something appears complex its yet to be understood...

Can anyone shed any light on future weather patterns for the uk In our local paper it is reported that we may be in for the coldest winter since records began, is this due to the ice caps melting, or is it a local phenomena?

Hey people :smile: , I have a question. Here is the Q: Question 3: (4 points) Many baby birds have specific feeding responses that are fixed action patterns elicited by a particular sign stimulus. Nestling starlings are more likely to make a fixed action pattern orienting response...

Are there any programs that can be used to find out what numbers have in common? eg, 748805534073 408986296450 445580425891 399528663101 571646773773 can't find anything to do it :confused: cheers

In researching the patterns in numbers that develop from expressing the relationship a number has with itself (1/n=N, NX2,3,4...n),in decimal form, I found a very interesting one. If you have read my threads on resonance in vibration, and the values of prismatic color, it will help with...

I have an idea that I've tried to express on this forum before but without success. There's a lot of reasoning behind the idea so it won't do no good just blurting it out. I want to lead you and see if you reach the same conclusion... So here goes... First question... In classical physics...

In a harbour, the time between successive high tides is 10 hours. On a day when the height of high tide above low tide is 8.0m, find (i) the angular frequency of the tides; (ii) the time interval within a cycle during which the sea-water is more than 5.0m above the low tide; (iii) the...

To know what I'm talking about you'll have to do a little experiment... Go to your bathroom, take some soap and foam up your hands. Make a "bubble" with your index finger and your thumb, then reflect the light from a lamp in the "bubble". After a little while oil-like rainbowcolored patterns...
