people say the worst SI unit is the mole. "ohhh but it's just a number it doesn't even have anything attached it doesn't deserve to be an official unit" BZZZ WRONG

the worst unit is the candela. the candela is stupid.

what's the candela, you ask? well, it measures the brightness of light

"oh that sounds reasonable" you say, "just measure the energy or power emitted!" nope. they would not do anything nearly so simple. a lightbulb emitting a watt of yellow light is more candelas than a lightbulb emitting a watt of red light.

"ok that's weird" you say, "but maybe they're adjusting for that somehow? maybe it measures number of photons?" again, that would be far too reasonable. a lightbulb emitting a fixed rate of yellow-light photons is more candelas than the same rate of purple-light photons.

but what are they even measuring then? what else is there to measure? clearly they ran out of ideas while making up units, because what they're actually measuring is the SUBJECTIVE BRIGHTNESS OF LIGHT TO THE HUMAN EYE. the candela is STUPID

a reasonable question to ask is: how would you even measure the brightness of light to the human eye? aren't a lot of human eyes different? don't different things look bright in different circumstances? aren't there colorblind people in the world?

surely the General Conference on Weights and Measures, which spent millions precisely calibrating magnetic quantum flux to avoid basing the kilogram on a random block in France, has a clever solution!

no. no they don't. the candela is stupid.

as far as I can tell, what you do is you first measure how much light of each wavelength comes in. Then you multiply each measurement by a "luminosity function", which measures brightness to the human eye:

you will notice that there are multiple functions shown in this diagram. the SI system has five of these, for different lighting conditions. do your lighting conditions not exactly follow one of the Five Official Standardized Lighting Conditions? guess you're out of luck then.

and whose eye are we using? why, the Official Standardized CIE Photometric Observer, of course: the "ideal observer having a relative spectral responsivity that conforms to a CIE-defined spectral luminous efficiency function for human vision"

(and no I can't show you this function because the fine people of the ISO put it BEHIND A PAYWALL. who puts measurements determining a fundamental SI unit BEHIND A PAYWALL. the candela is stupid)

all right, so we're measuring a fundamental unit using a (nonexistent) idealized observer in one of five random lighting conditions. how did they find the values for this? i'm...not entirely sure. but here's a glimpse, based on a few of the most recent studies I found used for this:

"...heterochromatic (minimum) flicker photometric data obtained from 40 observers (35 males, 5 females) of known genotype..."

"To obtain an estimate of the mean L-cone fundamental, we weighted [weird variables] according to the ratio of 0.56 L(S180) to 0.44 L(A180) found in the normal, male Caucasian population...and averaged them together"

that's right, our Official Objective Brightness Unit is probably sexist and racist. none of the other SI units have a chance to be sexist and racist. a meter is a meter in every country on Earth. 6.022*10^23 For Women is still 6.022*10^23. but the candela is-- probably-- the white man's candela, because you can absolutely bet that genetic drift around the world gives different values for this stuff.

in summary: my opinion, as you might have guessed, is that the candela is stupid. hopefully you agree with me after reading this that we need to completely eradicate it from the planet. failing that could we at not give it the same level of officialness as the meter or the kilogram?

A MISSING PIECE IN THE BIG BANG THEORY HAS SURFACED??

Blog#411

Wednesday, June 19th, 2024.

Welcome back,

Combining different pieces from Big Bang cosmology could help explain an issue we have today.

The Hubble constant, the speed of expansion of our universe, is not observed with consistency.

These scientists suggest that not-well-understood quantum gravity could account for the gap.

In research published earlier this year, physicists from the University of Hyderabad in India say they’re on the path to solving one of the universe’s biggest outstanding problems. Since Edwin Hubble realized the universe is always expanding nearly 100 years ago, scientists have used the “Hubble constant” in calculations on virtually every scale in the universe.

But today, estimates for the Hubble constant don’t always align, with a difference of up to 10 percent between calculations made using different methods. (When someone at NASA mixes up meters and yards and loses an entire spacecraft, that’s not even a full 10 percent deviation.)

The paper appears in the peer reviewed journal Classical and Quantum Gravity. The journal has an ongoing, periodically updated “focus issue” specifically about this measurement tension, and the editors explain the problem there—scientists can’t say for sure that the different Hubble constants measured are actually different, rather than just observation or calibration issues.

But the authors of the new paper, physicist P.K. Suresh and his research fellow (referred to as just Anupama B.) say that most measurements taken now are reliable. Instrumentation only continues to improve—we’ve all seen those generation-defining, poster-quality photos of the far-out planets, for example. If the measurements on the local and faraway levels are indeed sound, then something is missing.

It’s here where they introduce quantum gravity as a possible factor. This variable—which, to be honest, is another enigmatic “placeholder” in some ways—could close the gap in Hubble constant observations. That’s because, as the authors propose, quantum gravity could have affected the rate of change at which the universe expanded itself. When a constant can have a variable rate of change, it’s easy to see why researchers tend to drop the ‘constant’ label and instead call the fatcor simply H0, H1, and so on to designate which version of the measurement is in play.

The researchers explain that during inflation—the rapid growth of the universe immediately following the Big Bang—there may not have been a single, uniform inflation zone. Instead, more and more scientists are theorizing around the idea of “multi field” inflation. The idea originated to explain another measurement discrepancy: the number of particles in particular places or times, compared with the massive speed of inflation overall.

If a theory could help explain one gap in our codified equations for how inflation works, it makes sense to try that theory to find other missing pieces. These researchers used what is called the hybrid inflationary model, which describes two fields: one inflating and one rolling over like a waterfall. By accounting for quantum gravity, they found they were able to reconcile H0—the current Hubble constant—with both H1 (during inflation) and HT (during phase transition). Just one adjusted equation with a parameter for quantum gravity could draw a curve that includes all three data points.

"WHAT IS THE OLDEST BLACK HOLE IN OUR UNIVERSE??"

[daddysmusicblog]

Recording Studio Tech

⚠️ High pitched frequency warning! ⚠️ This frequency may trigger tinnitus.

This is the tedious work behind your favorite music that you rarely get to see. When i was an engineers apprentice, this was the sound that accompanied the start of every morning. In this video a studio apprentice is adjusting the calibration and alignment of the Studer A80 tape machine at Omega Recording Studio. The MRL Calibration Tape plays a 1khz frequency at 250nWb/m. The Weber is the unit of magnetic flux, or in layman’s terms, magnetic strength. It is an important measurement for getting signals on and off of magnetic tape (whether digital or analog). One Weber is much too large a unit to be relevant with tape recorders, so the nanoweber (one billionth of a Weber) is a standard unit of measurement. The recorded level of tape is expressed in nanowebers per meter of tape. Especially in analog recording, the signal level to tape is a critical component in the performance of the tape. Too high a level, and you get distortion  and lack of headroom, but with too low a level, your signal-to-noise is compromised. The proper recording level for tape depends a lot on the formulation of the tape and the electrical/magnetic characteristics of the recorder. Recorders are thus aligned using standard reference tapes containing tones at known levels rated in nanowebers per meter. Once the machine is calibrated to a reference, it becomes possible to optimize its levels for the particular formulation of tape desired through another alignment procedure. Recording to tape is just as much an artform as making the music itself.

Journal Week 12 - Master Bus

Why is gain staging important? Gain staging is about having enough level coming into the mixer that the audio engineer can work with while creating a mix. It is also managing the levels of each track to prevent any noise or distortion. It's about creating a mix that is louder, clearer, and more dynamic, and also having enough headroom so the master bus isn't peaking or distorting.

Why start with the low-end in your mix? The low end has more energy and is harder to control, I find it is also the sweetest spot where the toe-tapping starts, so getting this area right is very important. The lower frequencies can also take up a lot of the lower half of the EQ spectrum and mask other instruments in the process. Keeping the lower to upper mid frequencies clear can be more difficult.

What are some differences between a VU meter and a Peak Meter? The VU (Volume Units) metre is a representation of how the human ear hears sounds and is used to see the energy and intensity of a sound or track better. While a peak metre (True Peak) only measures the highest levels of a signal, and move around a lot more erratically than the VU meter. Peak Meters are good for seeing if there is any clipping in your track.

Where do you put your VU meter? The VU meter is applied to the master bus at the beginning of a mix

What is a suitable VU dB calibration level for people ‘listening at home’ and to get a track Mastered? Set the VU meter to -14db, then when mixing in each element of the mix make sure the VU meter is bouncing at around -5 db to -7db. This creates enough headroom for a better mix when it comes to the mastering process.

The MCT-2000 acoustic cavitation meter is a cutting-edge device designed to measure cavitation performance in ultrasonic cleaning and sonoprocessing tasks. When paired with the HCT-0320 hydrophone, it instantly calculates four primary parameters:

Base Frequency, FO

Initial Field Pressure, PO

Consistent Cavitation Pressure, PS

Short-lived Cavitation Pressure, PT

These measurements are derived from the calibrated acoustic spectrum, which identifies various pressure elements. Transducers produce mechanical sound waves that vibrate at the base frequency, leading to the initial field pressure. Swift pressure variations in the fluid form cavities, termed "cavitation". Consistent cavitation indicates a fluctuating cavity, causing micro-streaming effects. Short-lived cavitation emerges past a certain pressure level, causing the cavities to burst, leading to jetting actions and shockwaves.
