0:00:07a
0:00:12well i in this paper but we have to so what is your propagation mean
0:00:16but according to classical mechanics an object can be considered as a popular as a
0:00:19way to intrinsically conflicting quantities i really something localised some his position in space time
0:00:25can be determined at least continue subject result we want anybody can get a couple
0:00:30estimate the peaks
0:00:33on the contrary a way to something be localised something which extends over regions based
0:00:37on continuous unit amplitude as you
0:00:42however according to quantum mechanics things get really mixed up quickly and stein and with
0:00:47that of
0:00:48but if you believe the hypothesis of the priori a single particle can also behave
0:00:52that way
0:00:52right
0:00:54how can we experimentally that participated
0:00:57so we just let it interfere
0:01:00well as interference mean well as a child probabilities to menus first and what you
0:01:04generate imaginary into two openings each the secondary
0:01:10you know what happens then we can see that there is a complex
0:01:14at some positions where alright to get a combined to give more position
0:01:18in other places they combine class
0:01:20so we find that happened with the interference
0:01:26now imagine these profiles one of the other two same as well
0:01:30on the screen position on the other side you expect to see the fly was
0:01:32only behind the of every waves
0:01:37what if we never p the flower experiment but this time using one and l
0:01:42here but it when the lattice in which the same cluster
0:01:47okay but the client offices
0:01:51no fight intensity distribution it just like the way to syllable
0:01:56this means that the flat like to hear any propagating through the year
0:01:59this is something very low
0:02:03you want to automatically into problems that need really possible source of condom the house
0:02:07secondly of two or more openings and finally something the cat such as well as
0:02:12on the other side you
0:02:14a flower and assigned to individual molecules introduced to the cast a special kind looks
0:02:20like the one to go to the work
0:02:23that sounds good because when we make the data it will address
0:02:27like attacking this person's like with a microscope we can single molecules on the screen
0:02:31behind of this means we can initially interference
0:02:35the opening then we produce nanotechnology saying
0:02:38it's very regular
0:02:40let suppose we want to distinguish to interference fringes separated by one toolkit of a
0:02:44millimetre on a screenplay
0:02:47we consider a phallus are in line hundreds and second in use a separation of
0:02:52one hundred ninety min which is about ten times smaller than the diameter of your
0:02:57the second can you find an denigrating through in h
0:03:01well the of this
0:03:02this is the picture and superior to scale
0:03:05i mean
0:03:07it shows an enemy decide periodic architecture in two directions
0:03:11in particular we can see that the two hundred and five millimetre also another extraction
0:03:15hundred and twenty nine and importantly
0:03:19now what happens if we send of molecules one of the other three help can
0:03:22see interference
0:03:25we managed to look at the park who through the whole biological knowledge this is
0:03:30cool you might think you more camilla
0:03:33in order to this question that is focus on the diffraction is marked
0:03:38we take pictures the algorithm and then using the of a note the fraction into
0:03:41goes calculate and then actually intensity distribution then we compare this to what we see
0:03:45in order to things a clear
0:03:47but the whole the theory predicts a two-dimensional interference
0:03:50we only observe what image
0:03:52there's a simple explanation this gravity
0:03:55automotive supply from source to the fact that they only as gravitational field
0:04:00as a result if a lot these will contribute same spatial region why and how
0:04:04you know
0:04:05secondly and this is you can use interview at time is preserved
0:04:10but if we compare the data in addition in the theoretical simulation high interference as
0:04:16rumours missing
0:04:17it must be something else go here so what's the tree
0:04:20well run through the outer single molecules experience interaction potential surfaces
0:04:25this interaction by them on the balcony
0:04:28from an experimental point of view this interaction new make find affective reduction it's results
0:04:33in a larger population the high interference
0:04:36if we repeat the simulation but intuitively shrinking the opening the pool we can estimate
0:04:40an effective reduction is quite a teaching them
0:04:43alternatively we can repeat simulation anything terms we can estimate interaction constant between that assigned
0:04:50in the surface of the l
0:04:57i
0:05:03i am going
