Some New Binaural Beats


Binaural beats are created by playing a single frequency in one ear and a slightly different single frequency in the other ear. The difference between the frequencies create a noticeable beat pattern to the listener. Binaural beats are said to have therapeutic value.

Currently available binaural beats combine a single beat frequency with an ambient sound/song mixed in. This is fine, but I find that using this technique may not offer the desired full therapeutic effect. I see this as similar to taking a pharmaceutical drug, which is typically 1% active ingredients (a single kind of molecule) and 99% filler material.

My binaural beats does two things differently. First, there is no filler material. What you get is 100% pure binaural beats. Second, the beat frequency varies throughout the entire session. People are all different and therefore they respond to different beat frequencies. It’s arrogant for us to assume that specific frequencies effect everyone exactly the same way. Single frequencies create an audio experience that is fairly static. Using my binaural beats, the listener receives a variety of beats, similar to the “ensemble effect” in natural medicines where a plurality of molecules are synergistically mixed.

The varying beat frequencies are produced in a very unique way as well. I’ve taken the motions of astronomical objects (e.g., the four Galilean moons of Jupiter) and converted these into the individual frequencies for each ear. This provides a beat frequency that is slowly changing, and directly connects the listener to events happening in the universe. This also entrains the brain in different ways throughout the session, offering a richer and dynamic therapeutic experience.

The binaural beats that I offer can vary in base frequency, range of beat frequencies, and length of session. In this sense, the sessions are made to order. How the beating changes, though, is completely dependent on the motions (in this case) of the astronomical objects.

Astronomy Daily *Live* Every Day at 02:00 UTC

I'm jumping into a new realm of insanity.  Hope you'll join me on the ride!

Astronomy Daily *Live*

ADL is a casual, open-minded, skeptical, educational, and fun conversation about astronomy and related fields.  Whether you're a newbie, amateur, advanced amateur, or professional, please join me every day at 02:00 UTC starting on 14 January 2018.  Most conversations will be directed by the participants, but I'll usually have some topics in my back pocket to keep the conversation flowing.  Open topics can include Q&A, observing, gear, telescopes, cameras and other instrumentation, data analysis and research, journal paper reviews, personalities, astro-art, projects and institutions, and pretty much anything else the participants suggest.

Consider this as a daily gathering of friends to hang out and discuss topics of mutual interest.  Get away from the TV and the news for a while, and come talk live with people from all around the world who share a similar passion for astronomy!

Email cosmiclettuce AT gmail DOT com and I'll send you a link to become a panelist when the show goes live!

Continuing to Contemplate Galilean Moon Motion

I decided to see if there are any explanations for what the higher-order derivatives (3rd, 4th, 5th) of position actually feels like, and I didn't get much of an answer.  However, they all have names.  The best source of info on this subject that I was able to find is this article:

What is Derivatives Of Displacement?

So yes, the 3rd derivative is called 'Jerk', which I call 'Bump' -- it's a change in acceleration.  The 4th derivative is 'Jounce' (the change in the 'Jerk') and 5th derivative is called 'Crackle' (the change in the 'Jounce'), which to me don't relay any kind of physical sensation.

In the case of the motions of Jupiter's Galilean moons, I can now look at the past seven days of motion:

Galilean Moon Motion 08 June 2017

Looking at the motions of the four Galilean moons of Jupiter.  The following plots are for 08 June 2017.

In all of these plots, I'm showing the 0th (position), 1st (velocity), 2nd (acceleration), 3rd, 4th, and 5th derivatives of position as a function of time.  So the 0th derivative is in km, 1st is km/minute, 2nd is km/min^2, 3rd is km/min^3, 4th is km/min^4, and 5th is km/min^5.  What do the higher-order derivatives feel like?  Not sure, but the 3rd order probably feels like a bump (a change in acceleration).


Io motion around Jupiter:



Europa motion around Jupiter:



Ganymede motion around Jupiter:



Callisto motion around Jupiter:



Io motion relative to Europa:



Io motion relative to Ganymede:


Here's how the 4th derivative sounds:


Io motion relative to Callisto:



Europa motion relative to Ganymede:



Europa motion relative to Callisto:



Ganymede motion relative to Callisto:


All of this will be converted to audio so I can experience how it sounds.

Chaos Plots

These images are based on the equation:

N+1 = (lam) * N * (1-N)

where 'N' is the current population level (scaled between zero and one) and 'N+1' is the next population level.  'lam' goes from zero to about five until things get a bit crazy.

This little work is based on the video:

In the plots below, the x-axis is the 'lam' value, and the y-axis is the 'N' value.

CMS Audio and Visual

In today's Weekly Space Hangout, the guest was Elizabeth S. Sexton-Kennedy who works at Fermilab with the Compact Muon Solenoid (CMS).  I enjoyed the interview very much and it was a breath of fresh air to be focusing on non-astronomical topic that indeed has many astronomers very interested.  At one point in the interview, she very briefly but proudly mentioned that CMS data is available to the public.  I don't necessarily consider myself "The Public" but what I heard was that CMS data was publicly available.

So I started my hunt.  The goal was to see if I could take some CMS data and turn it into audio and visual interpretations.

It was pretty easy to find the data.  I had quite a choise so I just blindly chose the first one: "Dimuon events with invariant mass range 2-5 GeV for public education and outreach" which happened to be a file containing two thousand data points (maybe they're individual events????) that I haven't a clue about.  At the top of the .csv file is a very short header apparently describing the values therein.  I noticed that columns 4, 5, and 6 were labeled "px1", "py1", and "pz1".  So I'm sort of taking that as some sort of three-dimensional coordinate system.

I can work with that.

So what I did was a calculated the "distance" between each "event" coordinate and the origin (0,0,0 in 3D space), giving me a radial distance between the "event" and the origin.  I then sorted them by distance and translated those values into audio frequencies and came up with the following (in all of these cases, a lower frequency means a smaller distance; also note that I've kept the amplitude of each frequency the same):

This is the sound of the five hundred "events" that were nearest the origin.

CMS Dimuon 0 to 500

Here is the sound of the five hundred "events" starting at the 500th furthest one from the origin:

CMS Dimuon 500 to 1000

here is the sound of the five hundred "events" starting at the 1000th furthest one from the origin:

CMS Dimuon 1000 to 1500

here is the sound of the five hundred "events" starting at the 1500th furthest one from the origin:

CMS Dimuon 1500 to 2000

And here, at last, is all of them combined into one sound (2000 notes playing at the same time!):

CMS Dimuon All Events

Now of course I had to make some pretty pictures using the same data.  All I've done here is plot the values and in some cases connect the dots.  Hope you like 'em.  I think they're beautiful!

Looks like a white blood cell, a stange snowflake, or a spiney cotton ball
