A SINE curve ... not sin.

A sine wave or sinusoid is a mathematical curve that describes a smooth periodic oscillation. A sine wave is a continuous wave. It is named after the function sine, of which it is the graph. It occurs often in pure and applied mathematics, as well as physics, engineering, signal processing and many other fields. Its most basic form as a function of time (t) is:

{\displaystyle y(t)=A\sin(2\pi ft+\varphi )=A\sin(\omega t+\varphi )}
where:

• A = the amplitude, the peak deviation of the function from zero.
• f = the ordinary frequency, the number of oscillations (cycles) that occur each second of time.
• ω = 2πf, the angular frequency, the rate of change of the function argument in units of radians per second
• {\displaystyle \varphi } = the phase, specifies (in radians) where in its cycle the oscillation is at t = 0.
• When {\displaystyle \varphi } is non-zero, the entire waveform appears to be shifted in time by the amount {\displaystyle \varphi }/ω seconds. A negative value represents a delay, and a positive value represents an advance.
The oscillation of an undamped spring-mass system around the equilibrium is a sine wave
The sine wave is important in physics because it retains its wave shape when added to another sine wave of the same frequency and arbitrary phase and magnitude. It is the only periodic waveform that has this property. This property leads to its importance in Fourier analysis and makes it acoustically unique.

Oops. Spelling is not my strong point, but I’ll let auto correct take the fall here (but it was proabably me).

Protected by a 109,000-acre U.S. Army post in Kentucky sits one of the Federal Reserve's most secure assets and its only gold depository: the 73-year-old Fort Knox vault.

According to the U.S. Mint, there are currently 147.3 million ounces of gold in Fort Knox, KY. At an example price of about +/- $1,350 per ounce, this is worth give or take$198.86 billion dollars.

Sullysullinburg ... NO problemmo. I'm a retired math (and other stuff) teacher. I was having fun with that.

Yup, the mortgage industry was rife of shenanigans back then.

In addition to highly leveraged mortgages, those high flying mortgage companies started selling "Interest Only" mortgages pushing certain demographics ppl to those mortgages. Talk about lack of sustainability.

Oddly, unlike the above article, I know some ppl that have interest only loans today, from just a few years ago. So they are selling those to not only the rich, but also the ppl that should be renting instead of buying (if you want to call it that). If you miss/late for a payment you are now upside down on the loan without even paying any principal .. and you hope the property valuation goes up.

The mortgage industry loves to use future income potential in their calculations as they expand their business to drive revenue no matter the risk. It's up to the consumer to be educated and willing or not-willing to go for these types of debt capitalization.

Maybe we can buy tickets and go inside and check...LOL

Oh, I know perfectly well what a sine wave looks like. I bought my second oscilloscope when I was about your age.

What I'm balking at is the notion that the market is periodic, or predictable -- except in hindsight, which isn't really "prediction".
