In search of solid ground

rough-surf

About 6 or 7 years ago, StarMan and I found ourselves surrounded in way-too-high waves off the Florida Space Coast, stupidly trapped in a rip-tide.  I knew that we were in trouble approximately 20 seconds before he did.  We had been in the water for at least 40 minutes, laughing and enjoying the bouncy waves.  We were unaware that with each playful wave jump, we were getting carried a few feet further from shore.  The waves were tall and irregular that day, a fact that was made abundantly clear only after we were wore out and ready to go back to our beach towels.  Continue reading

Observations Of A Circuit Theory Lab Experiment (From the Perspective of the “Wire”)

Today, I had an EMG test in my neurologist’s office.  Goal?  Figure out what the eff is wrong with my right arm. It was the most un-fun visit I’ve had with Dr. K.  Things started out innocently enough … the nice chatty lab tech hooked up some electrodes along my arm, touched my arm in several places with what looked like the end of the power cord for a washing machine, producing a slightly uncomfortable but decidedly purposeful twitch in various parts of my person (confined, mostly any way, to the general vicinity of my arm). StarMan came along, for entertainment purposes.  He said that the scene reminded him of this:

Eye Am Stable?

Just a quick eye-health report. and its a good one.  I’ve had 2 OCT scans since I last reported on my eye condition.  I saw a new neuro-opthomologist back in the spring, at UCSF, and then back to my optometrist last month.  As usual, I give you a summary of all the OCT measurements so far:

Taking Heart

I’m convinced that blog post ideas are a lot like the weather: when it rains, it pours!  I’ve got at least a half-dozen, half-baked posts in my head right now, and no time to spill them out “on paper”.  But I do need to take a few moments to write about my latest cardiologist visit, before the details are lost in the cobwebs of my mind. Continue reading

Results Still TBD, But TIA?

In my last post, I had planned on reporting on a visit to the cardiologist’s office, but sad news of my primary care physician’s sudden death (the same person who had given me a referral to the cardiologist) sent my post in a different direction.   Here, I’m going to describe what happened that day, once I saw the cardiologist.

A Matter Of Uncertainty

As a wide-eyed undergraduate physics student getting introduced to scientific research, the following proverb was drilled permanently into my head:  no measurement we could possibly make in this imperfect world — the cup of flour that our recipe calls for, the pencil marks on the wall indicating the annual growth of our child, the 10 gallons of gas that we were led to believe just went into our car tank — is ever exactly the “true” measurement, but rather is a value with some “give or take” (aka, uncertainty) associated with it.  And that amount of tolerance shall always be attached to any measurement! After my recent OCT eye scan last week, I’m wishing that students in the medical field had the same borderline-unhealthy obsessions about uncertainty. Continue reading
