The primes are "suspicious  solitary numbers " Giordano writes. Perhaps they would prefer to be ordinary numbers  "but for some reason they couldn't do it." And he elaborates: There are some that almost touch -- 17 and 19  41 and 43 -- but are separated by an even number. As the numbers expand  these so-called twin primes become ever rarer  and the presentiment develops that these were accidents  and "that solitude is the true destiny." But then  if you count long enough  you'll find another pair of twins  "clutching each other tightly." Giordano depicts with aching vividness the traumas out of which Alice and Mattia emerge disabled. Alice's ski fall might be only that  despite a permanently crippled leg. But we get horror seen from within: a father who bullies her  even if lovingly  into enduring the cold  the awkwardness  the fear of something she has so little taste for that she humiliatingly befouls her ski pants. Adults cannot suspect what furnishes a child's nightmare; here  the reader is made to live it.
 Giordano remarkably and movingly portrays the hesitant groping toward warmth that works beneath the pair's emotional disabilities. Alice  unable to tolerate not just food but also the vitality it stands for  assumes a touchingly decisive if frail seductiveness with the shaky Mattia. When at 22 he brings himself to tell her about his sister  she embraces him  they kiss  and for a moment it seems things will change.
 Only briefly; Mattia retreats  goes off to Scandinavia. Upon his return years later there is another almost-moment. That too will vanish. Alice's reaching out  though tentative  is genuine. His response describes a parabola: rising  seeming to converge  dropping away. He is the man who fell to earth; she is earth  though crumbly.
 What is even more distinctive  and transforming  is the writing. The author works with piercing subtlety. He manages -- moving from math to physics -- an exquisite rendering of what one might call feelings at the subatomic level  emotion's muons  gluons and quarks. Take that kiss: "All Mattia saw was a shadow moving toward him. He instinctively closed his eyes and then felt Alice's hot mouth on his  her tears on his cheek  or maybe they weren't hers  and finally her hands  so light  holding his head still and catching all his thoughts and imprisoning them there  in the space that no longer existed between them."

BEIRUT (Reuters) - Lebanonâs Shiâite Hezbollah group on Sunday accused Saudi Arabia of forcing  Lebanese Prime Minister Saad al-Hariri  to quit  and called for calm in an effort to contain the political crisis unleashed by  his  resignation.

Sayyed Hassan Nasrallah  the leader of Iran-backed Hezbollah  said there should be no political escalation in response to  Hariri âs declaration on Saturday  which was made from Saudi Arabia and came as surprise even to his aides.
 Hariri   in a televised speech  said there was a plot to kill him  and accused Hezbollah and its Iranian backers of sowing strife in the Arab world.
Nasrallah said âlegitimate questionsâ were being asked over whether  Hariri  had been detained in Saudi Arabia  where news emerged on Sunday that royals  ministers and investors had been arrested in an anti-corruption purge.
Speaking in a televised address  Nasrallah said: âThe resignation was a Saudi decision dictated to  Prime Minister Saad al-Hariri  and was forced on  him .â
Nasrallah said Lebanonâs political leaders expected  Hariri  to return to Lebanon on Thursday âif  he  is allowedâ to travel.
Sunni Muslim Saudi Arabia  a political ally of  Hariri   is locked in a bitter tussle for power across the Middle East with Shiâite Iran and its allies  including Hezbollah.
Lebanese President Michel Aoun will not accept  Hariri âs resignation until  he  returns to Lebanon to explain his reasons  palace sources said on Sunday  delaying for now the politically difficult consultations over his successor.
Nasrallah said he would not comment on accusations leveled against Hezbollah by  Hariri   describing his resignation announcement as a Saudi statement.
 Hariri âs resignation toppled a coalition government that included Hezbollah  thrusting Lebanon back into the frontline of the Saudi-Iranian regional rivalry and risking an open-ended political crisis.
Nasrallah said he had thought things were going well and had not wanted  Hariri  to quit.
 Hariri  allies in Lebanon have denied suggestions he had been detained and a photograph was published on his Twitter account showing him with Saudi Arabiaâs newly appointed ambassador to Lebanon  Walid al-Yaaqoub.
News of high-level arrests in Saudi Arabia fueled social media speculation in Lebanon that Hariri  a Saudi national  was a target. Nasrallah said âthere was legitimate concernâ  asking if  Hariri  had anything to do âwith this internal struggle between the princesâ.
Saudi-owned newspaper Asharq al-Awsat cited unnamed sources close to  Hariri  as speculating that  he  would probably remain outside Lebanon because of the security threat against  him .
In Lebanonâs sectarian system the president must be a Maronite Catholic  the prime minister a Sunni and the speaker of parliament a Shiâite.  Hariri  is Lebanonâs most influential Sunni politician.

Ideas for research projects can germinate from the least likely moments  as when a student asked  Firearms Trainer Tom Aveni  if he'd ever visited the ACLU's website. He hadn't ("Why would I even want to go there?")  but out of curiosity he did.
Not only did the ACLU statistic turn out to be not as far off as he imagined but  Aveni  has made other unexpected discoveries - pertaining especially to hit ratios  low-light shootings  multiple-officer confrontations  mistaken judgment calls and less-lethal technology - that have convinced him police firearms training needs a significant overhaul.
Dr. Bill Lewinski  executive director of the Force Science Research Center at Minnesota State University-Mankato  says that by pursuing "important and different kinds of questions "  Aveni  has produced "valuable new insights into officer-involved shootings." His findings are expected to provide "a cutting-edge demographic foundation" for upcoming research projects at FSRC that hopefully will result in "profound changes in law enforcement training in the future."
An ex-cop with 23 years' training experience   Aveni  now heads the Police Policy Studies Council  a research  training and consulting corporation based in Spofford  NH  and is a member of FSRC's National Advisory Board  as well as a busy expert witness in police litigation. Like other trainers   he  says   he  "made a lot of assumptions that are not true" until  his  research provided "an epiphany for  me " about some of the nuances of police shootings.
 He  was struck first by how tough it is to find out anything meaningful on the subject from law enforcement agencies. Most don't compile detailed data on their shootings  fearing in some cases (perhaps rightly) that it would be misinterpreted and misused by the media and "agenda activists" if available. Of the few departments that do collect deadly force information  "even fewer freely share it " Aveni claims. If they don't outright suppress it  they tend to present it in bare-bones  "sterilized table formats" that have no standardized consistency and that "make detailed analysis difficult."  Aveni  observes: "The devil is in the details  and the details of police shootings have always been lost."
 Aveni  spent more than 6 months dissecting that material according to different variables. That information  combined with limited statistics  he  managed to obtain related to shootings on other major departments  including New York City  Baltimore County (MD)  Miami  Portland (OR) and Washington (DC)  has allowed  him  to spotlight a number of deadly force subtleties that have not been so thoroughly examined before.
For example  it has long been believed that officers overall have a dismal 15-25 percent hit probability in street encounters  suggesting truly poor performance under the stress of a real shooting situation. Actually  this figure  while essentially true in the aggregate  is markedly skewed by certain shooting variables   Aveni  found.
During a 13-year span  the Baltimore County PD  which  Aveni  regards as one of the best trained in the country  achieved an average hit ratio of 64 percent in daylight shootings - not ideal  but clearly much better than commonly believed. In shootings that occurred in low-light surroundings  however  average hits dropped to 45 percent  a 30 percent decline. The data from Los Angeles County (LAC) reveals a somewhat comparable 24 percent decline.
"Until this research "  Aveni  says  "performance has never been accurately matched to lighting conditions " even though as many as 77 percent of police shootings are believed to occur under some degree of diminished lighting. Some departments tally "outdoor" versus "indoor" shootings  but most appear not to precisely differentiate between low-light and ample-light events  despite the preponderance of shootings during nighttime duty tours.
A multiple-officer shooting  in which more than one officer fires during a deadly force engagement  has an even greater influence on hit probability   Aveni  discovered.
Multiple-officer shootings   Aveni  told Force Science News  are three times more likely to involve suspects with shoulder weapons than single-officer shootings. This tends to "increase the typical stand-off distance " he says. Many of these confrontations also embody fast-changing  chaotic and complex circumstances. These factors  Aveni believes  help explain the negative impact on accuracy.
 Aveni  also discovered a correlation between multiple-officer shootings and number of rounds fired.
With LAC shootings involving only one officer  an average of 3.59 police rounds were fired. When 2 officers got involved  the average jumped to 4.98 rounds and with 3 officers or more to 6.48. "The number of rounds fired per officer increases in multiple-officer shootings by as much as 45 percent over single-officer shootings  " Aveni  says.
The ACLU's statistic that got him started on this project turned out to be based on fatal shootings that occurred before the landmark Supreme Court decision Tennessee v. Garner  when nearly half the states still legally permitted the shooting of any fleeing felon  regardless of the threat he or she presented. After the restrictions imposed by Garner  "you'd expect fewer unarmed suspects to be shot "  Aveni  explains.
Not necessarily true  though   Aveni  found. In a recent 12-year period  Metro-Dade (Miami) PD reported 34 shootings in which suspects were "clearly unarmed" or in which officers thought they saw a gun but none was found. All told  about a third of all shootings in which suspects were shot and killed by that agency's officers were considered "questionable." In a recent Texas study  25 percent of suspects shot by officers in one metropolitan county were found to be unarmed  33 percent if shots fired at moving vehicles are included. LAC's data put the unarmed target figure at 18 percent  well below the ACLU's pre-Garner assertion.
Higher or lower  many of these shootings are "mistake-of-fact" (MOF) situations   Aveni  says. Usually a suspect is displaying an item that is falsely but reasonably perceived to be a deadly weapon (a cell phone  for example)  or the suspect is behaving in such a way that in context is believed to constitute an immediate lethal threat (making a fast  furtive movement toward the waistband  for instance).
