The Tampa Bay Rays are an American professional baseball team based in St. Petersburg, Florida. The Rays compete in Major League Baseball (MLB) as a member club of the American League (AL) East division. Since its inception, the team's home venue has been Tropicana Field.
Following nearly three decades of unsuccessfully trying to gain an expansion franchise or enticing existing teams to relocate to the Tampa Bay Area, an ownership group led by Vince Naimoli was approved on March 9, 1995. The Tampa Bay Devil Rays began play in the 1998 Major League Baseball season.
Their first decade of play, however, was marked by futility; they finished in last place in the AL East in all but the 2004 season, when they finished second to last. Following the 2007 season, Stuart Sternberg, who had purchased controlling interest in the team from Vince Naimoli two years earlier, changed the team's name from "Devil Rays" to "Rays", now meant to primarily refer to a burst of sunshine rather than a manta ray, though a manta ray logo remains on the uniform sleeves. The 2008 season saw the Tampa Bay Rays post their first winning season, their first AL East championship, and their first American League Pennant (defeating the rival Boston Red Sox in the ALCS), though they lost to the Philadelphia Phillies in that year's World Series. Since then, the Rays have played in the postseason five more times, winning the American League pennant again in 2020 and losing to the Los Angeles Dodgers in that year's World Series.
The Tampa Bay Rays' chief rivals are the Boston Red Sox and the New York Yankees. Regarding the former, there have been several notable on-field incidents. The Rays also have an intrastate interleague rivalry with the National League (NL)'s Miami Marlins (originally the Florida Marlins), whom they play in the Citrus Series.
Through 2020, the Rays' all-time record is 1,726-1,896 (.477).
What effect would a convex (concave) lens have on paraxial rays?
For a convex lens, the rays would pass through and converge on the focus on the other side.
For a concave lens, the rays would reflect back to the focus on the same side.
Is this correct?
So i have a question regarding a homework question I'm working on which suggest a neutral pion traveling with velocity v decays into two gamma rays of equal theta to the normal and they of course have velocity c. It then asks to prove that
v= cos theta

Hello, I was doing a little research on nanotubes and came up with an idea.
If we shot a cylindrical beam of electrons a few nanometers apart from each other and then shot a carbon plasma down the center would the carbon atoms be attracted to the electrons and form a nanotube at a sizable scale?
I've heard of cosmic rays affecting measurements made at the LHC in the context of muons. Is it just muons that can reach the detectors or is there background from other particles as well? Why are muons a background but not electrons? How significant is it?
