Inferno Producers to Lindsay Lohan: You're Fired!

Lindsay Lohan playing Linda Lovelace seemed too perfect, but it wasn't meant to be. The producers of Inferno are going in a new, less-troubled direction.
"We are withdrawing our offer from Lindsay Lohan," director Matthew Wilder said.
While it may seem a harsh rebuke of Lohan, who is currently in rehab at the Betty Ford Center, the director says it's not personal, it's just business.

EXTINGUISHED: Guess they're gonna need a new poster.
"We have stuck by Lindsay very patiently for a long time with a lot of love and support," said Wilder, who hinted last week that Lindsay might lose the role.
"Ultimately, the impossibility of insuring her - and some other issues - made it impossible for us to go forward." Yep, an indefinite stay in rehab will do that.
An announcement on her replacement is imminent. "We are in negotiations [with another star] and working out the legalities of bringing her onboard."
Who do you think it is? Can anyone replace Lindsay?

Benitez pins hopes on Champions League

Inter Milan coach Rafael Benitez is pinning his hopes on a Champions League victory over FC Twente in midweek to arrest an alarming slide that seems to have put his job at risk.

Prior to Sunday's 2-1 defeat at Chievo, the Italian press had given Benitez two games to save his job.
And having lost the first of those, even Benitez had to admit he needs to win on Wednesday.
"I'm a professional with many years of experience and I know that I must simply prepare for the matches and that's it," he said.
"If we win on Wednesday, everything will change.
"We need to score goals to win games.
"On Wednesday we have an important match and we have to stick together.
"We're in trouble but we've got many players out injured and we have to manage this moment."
It is true that Inter have a long injury list with the likes of Diego Milito, Maicon, Julio Cesar, Walter Samuel, Coutinho, Thiago Motta, Muntari Sulley and McDonald Mariga all missing against Chievo.
But they could still call on Serie A top scorer Samuel Eto'o to notch his ninth league goal of the season and 18th in all competitions.
That came deep into injury time with Inter already deservedly 2-0 down to strikes from Sergio Pellissier and Davide Moscardelli.
But Eto'o should not have been on the pitch at that point having got away with a blatant, deliberate headbutt on Chievo centre-back Bostjan Cesar on 36 minutes.
Benitez admitted his star Cameroon forward had lost his cool but he also claimed Cesar should have been punished too.
"I didn't see it," claimed Benitez before being shown the video evidence.
"It's clear he was punched and he's had this reaction that no-one likes to see but it's the reaction of a team needing to win.
"There are four officials at the game and if they don't think it deserves punishment then that's it.
"He's lost a bit of control that's clear but none of the officials took action."
As for the game itself, Benitez somehow managed to praise his misfiring team.
After last season's treble under predecessor Jose Mourinho, Inter's start to this campaign has been a disaster.
They have just five wins and 14 goals in 13 league matches, leaving them sixth in the table and nine points off arch rivals AC Milan at the top.
And yet Benitez preferred to praise his team's spirit.
"It's clear that after a defeat no-one is happy, the only thing I can say is that we worked very hard and our reaction in the second half on a terrible pitch showed great character," he said.
"I can't say anything against my team, the work ethic and attitude is there.
"We showed character, attacked all the time, took risks and if we'd have scored (at 1-0) that would have changed everything.
"This is football, when things aren't going well and you're playing with young players and needing to score, it's always more difficult to manage a game.
"Obviously we have to win these types of games because we're a strong team but we showed that we have the desire to win."
For his part Chievo coach Stefano Pioli played down the Eto'o headbutt.
"I didn't see it, I heard about it from other players and staff on the bench but for sure I prefer a different type of mentality," he said before turning to his own team's performance.
"We knew we could get chances if we could get the ball forward quickly because they attack with a lot of players.
"Inter approached the game well, they fought hard on a tough pitch but we were always quite compact, we played with a high tempo so it was hard for Inter."
Chievo are now just a point behind Inter and Pioli could not help but turn the knife in Benitez's wounds.
"It's a very tight league and even a team like Inter can have difficulties but I have to say, this isn't the Inter of last season that won everything."

Oksana Grigorieva to Lawyer: ONLY $15 Million!?

Oksana Grigorieva disavowed the $15 million settlement her lawyers got from Mel Gibson this spring not because she feared for her baby daughter, as she says, but because she felt the actor would pay a lot more to avoid the bad publicity.
We're not lawyers, but ... sounds a little like extortion to us.
A text sent June 2 from Oksana to Eric George, the lawyer who negotiated her $15 million mediation package, is laden with buyer's remorse, complaining that George never told her about a domestic violence claim, which could up the ante.
Underscoring how important the Mel Gibson tapes were in the mediation, Oksana says, "Forget about the tapes for the moment. This is the case of domestic violence."
The point - no one raised the issue of domestic violence during the mediation - it was about the tapes. Seriously shady stuff here. Was it ever really about poor Lucia?
Oksana says her relationship with Mel ended due to"Mels (sic) domestic violence, the only reason and the fact, with proof, and I run away to save my children."
Then she lays her cards on the table: "If the opposition is buying my silence, please, we have to renegotiate the custody portion and secure the monetory (sic)."
Also in the text, Oksana Grigorieva makes it clear she had a strategy all along, and aware of her strongest bargaining chip: "He doesn't want this publicity."
"I have lots of questions about the moneytory (sic) part also, i'd (sic) like us to get together and discus (sic) everything," she adds, "I am not bluffing."
Law enforcement sources say the text is part of the extortion investigation to determine if Oksana leveraged the tapes to score the $15 million package.
The theory: After signing the agreement, Oksana got greedy and decided she could get more than $15 million by adding a fresh domestic violence claim.
Was that whole "fearing for her life" bit all an exaggeration to get paid? No matter what Mel did, it's getting hard to take anything Oksana says seriously.
In other news, Mel will be front and center in court Monday as his lawyers ask the judge to strip Oksana of custody and award it to him. He'll be there in person because he wants to show how serious he is and how unstable she is.

Wesley Snipes: Finally Headed to Jail

He may have proven that white men can't jump, but Wesley Snipes has also made it clear that felons can't avoid jail time.
The actor - who was convicted of tax evasion in 2008, but spent years going to extreme lengths to avoid his sentence - had his latest appeal rejected by a federal judge this week.
Told he “had a fair trial” and that “the time has come for the judgment to be enforced,” Snipes will finally be heading to the clink.
“Wesley is very disappointed but staying strong and positive,” his lawyer told The Orlando Sentinel.
It’s unclear when or where Snipes will start serving the sentence. So much for always betting on black, though.

Anne Hathaway Makes Pitch to Glee Producers: Cast Me!

Anne Hathaway took a break from posing topless this week to make a pitch to Fox: the actress wants to be on Glee!
But Hathaway has already done the work for creator Ryan Murphy. She already knows what character she wants to portray:
"I would want to be Kurt's aunt," she told reporters this week. "I have thought about it... I would like to pitch to Murphy right now that I go on as Kurt's aunt, his mother who is deceased's younger sister."
Watch Hathaway and Gyllenhaal in the trailer for Love and Other Drugs NOW and then sound off: Do you wanna see Anne Hathaway on Glee?

Diffraction

In this lab the phenomenon of diffraction will be explored. Diffraction is interference of a wave
with itself. According to Huygen’s Principle waves propagate such that each point reached by a
wavefront acts as a new wave source. The sum of the secondary waves emitted from all points on
the wavefront propagate the wave forward. Interference between secondary waves emitted from
different parts of the wave front can cause waves to bend around corners and cause intensity
fluctuations much like interference patterns from separate sources. Some of these effects were
touched in the previous lab on interference.
In this lab the intensity patterns generated by monochromatic (laser) light passing through a single
thin slit, a circular aperture, and around a opaque circle will be calculated and experimentally
verified.

The intensity distributions of monochromatic light diffracted from the described objects are based
on:
a) the Superposition Principle
b) the wave nature of light
Disturbance: A = A0 sin (wt + €)     w for Omega, € for teta (angle on degrees)
Intensity: I = (EA)2    E for Sigma
c) Huygen’s Principle -- Light propagates in such a way that each point reached by
the wave acts as a point source of a new light wave. The superposition of all these
waves represents the propagation of the light wave.
All calculations are based on the assumption that the distance L between the slit and the viewing
screen is much larger than the slit width a:, i.e. L >> a. This particular case is called Fraunhofer
scattering. The calculations of this type of scattering are much simpler than the Fresnel scattering
in which case the L >> a constraint is removed.

Experiment 1 : Single Slit Diffraction
Theory
A narrow slit of infinite length and width a is illuminated by a plane wave (laser beam) as as shown in Figure 1. The intensity distribution observed (on a screen) at an angle q with respect to the incident direction is given by equation (1). This relation is derived in detail in the appendix and every student must make an effort to go through its derivation. The mathematics used to calculate this relation are very simple. The contributions from the field at each small area of the slit to the field at a point on the screen are added together by integration. Squaring this result and disregarding sinusoidal fluctuations in time gives the intensity. The main difficulty in the calculation is determining the relative phase of each small contribution. Figure 2 shows the expected shape of this distribution. 

Diffraction Single slit



yielding the following condition for observing a minimum light intensity from a single slit:


This relation is satisfied for integer values of m. Increasing values of m give minima at correspondingly larger angles. The first minimum will be found for m = 1, the second for m = 2 and so forth. If 
is less than one for all values of q, there will be no minima, i.e. when the size of the aperture is smaller than a wavelength (a < l). This indicates that diffraction is most strongly caused be perturbances with sizes that are about the same dimension of a wavelength.



Procedure
Two single slits (along with some double slits) are on a slide similar to the one diagrammed in Figure 3. To observe diffraction from a single slit, align the laser beam parallel to the table, at the height of the center of the long slide, as shown in Figure 4. The diffraction pattern you are expected to observe is shown in Figure 5.

1a) Observe on the screen the different patterns generated by both of the single slits of this slide.
1b) Calculate the width of each one of the two single slits. This quantity can be calculated fro

Equation (2) using measurements of the spacing of the intensity minima. The wavelength of the
HeNe laser is 6328Å, (1Å º 10-10 m). The quantity to be determined experimentally is sin q. This
can be done by trigonometry as shown below:

Measure the slit width using several intensity minima of the diffraction pattern.This measurement can be done using the screen covered with white paper. With a sharp pencil mark the position of the diffraction minima and then measure their relative distance with the ruler. To improve the accuracy of your measurements make the distance from slit to screen as large as possible. Compare your result with those given in Figure 1.
Enough for this time, next...Experiment 2 : Diffraction by circular aperture
