If you filed your Form N-400, Application for Naturalization, on or after December 1, 2020, and before March 1, 2021, and were scheduled for your initial examination (interview) before April 19, 2021, you may choose to take the 2008 or 2020 civics test as you go through the naturalization process. All others will be required to take the 2008 civics test.

The civics test is an oral test and the USCIS officer will ask you to answer 20 out of the 128 civics test questions. You must answer at least 12 questions (or 60%) correctly to pass the 2020 version of the civics test.

On the civics test, some answers may change because of elections or appointments. Visit our Check for Test Updates page to find any answers that may have changed on the civics test. You must answer the question with the name of the official serving at the time of your naturalization interview.

65/20 Special Consideration If you are 65 years old or older and have been living in the United States as a lawful permanent resident of the United States for 20 or more years, you may study just the 20 questions that have been marked with an asterisk (*) found at the end of each question. You may also take the civics test in the language of your choice. The USCIS officer will ask you to answer 10 out of the 20 civics test questions with an asterisk. You must answer at least 6 out of 10 questions (or 60%) correctly to pass the 2020 version of the civics test.

The Mp3 Experiment is a participatory audio adventure where attendees listen to synchronized secret instructions in a public space via headphones. We stage a new Mp3 Experiment in New York each year and also tour the project to college campuses and festivals around the world.

600 participants gathered in four different locations in the northwest corner of Central Park. Led by more ridiculous costumed characters (this time a giant Sun, Cloud, Raindrop, and Snowflake) the groups paraded through the woods to meet up with each other by a beautiful lake. An epic battle between the elements took place and everyone celebrated by forming a 600-person conga line.The Mp3 Experiment 2.0 (2005)

The original Mp3 Experiment took place indoors at the Upright Citizens Brigade Theatre. The audience watched a projected countdown clock and then all pressed play together. A few minutes later the seats were empty as the entire crowd was dancing on the stage. Participants blew bubbles, hit balloons in the air, and hugged each other before being led by Santa Clause (Agent Wimpy in costume) out the theatre and down the street to a nearby bar. A 13-minute video of the project exists and was available on our first DVD (long out of print).

A 2003 display for the iTunes Music Store ushers in a new age for the music business, shortly after its introduction. The iPod helped turn around Apple's fortunes and brand identity, while the creators of the MP3 had regarded a portable player as a mere storage device. Justin Sullivan/Getty Images hide caption

So opens Stephen Witt's How Music Got Free, an investigation into the forced digitization and subsequent decimation of the music business, from which it has only very recently started to recover. That ironic conference room eulogy actually took place just before the compression algorithm caught on (don't worry, we'll explain in a bit). Soon, the MP3 not only upended the recording industry but, thanks to the iPod, also contributed to Apple's late-'90s transformation into one of the most successful companies in history. (On Tuesday, the tech giant passed $800 billion in market capitalization, the first U.S. company to do so.)

But now, 22 years later, the MP3 truly is dead, according to the people who invented it. The Fraunhofer Institute for Integrated Circuits, a division of the state-funded German research institution that bankrolled the MP3's development in the late '80s, recently announced that its "licensing program for certain MP3 related patents and software of Technicolor and Fraunhofer IIS has been terminated."

In early 1995, the format was on life support, with one licensing deal being the use of the technology by hockey arenas across the U.S. (That spring meeting in which the MP3 was declared dead came months later, after another failed pitch that denied it being standardized and widely adopted.) A little later, Fraunhofer began giving away the software that consumers needed to turn compact discs into MP3s at home. The rest is recent history.

And it's not just that more efficient and complete ways of storing music have been developed. There was a deeper problem. The engineers who developed the MP3 were working with incomplete information about how our brains process sonic information, and so the MP3 itself was working on false assumptions about how holistically we hear. As psychoacoustic research has evolved, so has the technology that we use to listen. New audio formats and products, with richer information and that better address mobile music streaming, are arriving.

The formats that convey art and media to us also delineate that media; vinyl records require a session-interrupting flip, which The Beatles brilliantly exploited by creating an infinite loop of gibberish at the end of Sgt. Pepper's second side. The VHS tape in both image and sound was as soft and fuzzy as a worn teddy bear, while new high-definition televisions render images perhaps too robotically, tracking movement like T-1000. The MP3, as mentioned, enabled millions or billions of song listens, just with incorrect biological assumptions. The lesson seems to be, simply, that our media will always be as exactly imperfect as we are.

Besides these main features Mp3tag offers a variety of other functions and features rangingfrom batch export of embedded album covers, over support for iTunes-specific tags likemedia type or TV Show settings, to combining multiple actions into groups that can be appliedwith a single mouse click.

Study design: We conducted a qualitative analysis of focus-group discussions with adolescents aged 12 to 18 years from 2 large secondary schools (1 urban and 1 rural) for pre-vocational and pre-university education. The semi-structured question route was theoretically framed within the protection motivation theory.

Results: Most adolescents-especially male students and students from pre-vocational schools-indicated that they often played their MP3 players at maximum volume. Although they appeared to be generally aware of the risks of exposure to loud music, they expressed low personal vulnerability to music-induced hearing loss. Most adolescents said that they would not accept any interference with their music-exposure habits.

Conclusions: Interventions should target students from pre-vocational schools and should focus on increasing adolescents' knowledge of the risks of loud music and how to protect themselves. Besides hearing education for adolescents and technical modifications of MP3 players, volume-level regulations for MP3 players may be warranted.

Multi-petawatt laser systems can produce light pressures in the exa-Pascal regime, copious amounts of radiation, and extremely bright beams of energetic particles, including electrons, ions, neutrons, or antimatter. These novel capabilities enabled by multi-PW lasers, described in a series of recent reports shown below, open new frontiers in research and development, such as high-field physics and nonlinear quantum electrodynamics (QED), laboratory astrophysics, particle acceleration and advanced light sources, and laser-driven nuclear physics.

The Multi-Petawatt Physics Prioritization (MP3) Workshop will bring together scientific communities to focus on promising new science enabled by a new generation of ultra-intense and powerful lasers. The workshop and a series of virtual working group meetings leading to it will establish and develop networks of researchers who will recommend ways to coordinate research and broaden access to state-of-the-art facilities, diagnostics, and computational tools for high-intensity laser-based research.

Control quality with -qscale:a (or the alias -q:a). Values are encoder specific, so for libmp3lame the range is 0-9 where a lower value is a higher quality. 0-3 will normally produce transparent results, 4 (default) should be close to perceptual transparency, and 6 produces an "acceptable" quality. The option -qscale:a is mapped to the -V option in the standalone lame command-line interface tool.

If you need constant bitrate (CBR) MP3 audio, you need to use the -b:a option instead of -qscale:a. Here you can specify the number of bits per second, for example -b:a 256k if you want 256 Kbit/s (25.6 KB/s) audio. Available options are: 8, 16, 24, 32, 40, 48, 64, 80, 96, 112, 128, 160, 192, 224, 256, or 320 (add a k after each to get that rate). So to get the highest quality setting use -b:a 320k (but see note below).

The SparkFun MP3 Player Shield is an awesome MP3 decoder with the capabilities of storing music files onto a run-of-the-mill microSD card, thus giving you the ability toadd music or sound effects to any project. With this board you can pull MP3 files from an microSD card and play them using only one shield, effectively turning any Arduino into a fully functional stand-alone MP3 player! The MP3 Shield utilizes the VS1053B MP3 audio decoder IC to decode audio files. The VS1053 is also capable of decoding Ogg Vorbis/MP3/AAC/WMA/MIDI audio and encoding IMA ADPCM and user-loadable Ogg Vorbis. 350c69d7ab
