My deepest condolences to the family. It is a tragic loss to his family and another great member of PF saying goodbye in the saddening way possible (I remember about self Adjoint years ago).
My condolences, Marcus was always able to supply excellent counter points to LCDM in LQC based models. I always enjoyed his counter points to numerous threads where I've supplied one variation to an answer, then he supplied another.

I also enjoyed working with him on the lightcone tutorial development. He had a natural way to extend the flexibility of the calculator well beyond its first appearance.
His true gift was simplifying the complex mathematics for numerous posters who didn't have strong math skills.

He will be missed.
What sad news. My deepest condolences go out to Marcus's family, friends and everyone whose lives he touched. I'm deeply indebted to him for his patience and knowledge which have helped me to understand some of the complexities of our wonderful Universe.

RIP Marcus.

I never really interacted with Marcus, though I read many of his threads ... I'm sorry for the loss of this intelligent mind! @tamwuff May your family heal and receive comfort from those around you.

Though I must say, this is just more proof that PF is such a splendid community--to remember it's members once they have passed.
I know of little else that impacts humans as deeply as death because we all seem so helpless in the facing of it. I am very grateful that you, tamwuff, saw fit to let us know some details during your time of grief. I find that a bit heroic and also somewhat understandable given the influence of a good man like Marcus. Please accept my deeply sincere expression of love and respect for your father for all his drive to share his knowledge so unselfishly. Also trust that once the physical process of grief has has diminished, while you will forever miss him as so many of us here will, you, like us, will find that grief ultimately greatly outpaced by the goodness and brightness of the man and the manner of life he apparently led. This thread is certainly testament to a major aspect of that. Peace to you and yours.

How very sad. Marcus was one of the very first members to welcome me to PF (perhaps because of our shared name, which he commented on). His intellect, patience and professionalism will be missed.
This is very sad, and a stark reminder of our own transience and mortality. I have not known him for long, but it is safe to say that not only did a remarkable human being pass on, but along with him also an incredible amount of knowledge and understanding on this universe we are all part of. A lifetime to accumulate, yet lost in a moment.

RIP, and condolences to his family and friends.
My sincerest condolences to tamwuff and the rest of his family.

He is a legend, like his favourite Marcus, Marcus Varro (Varro Reatinus), the most brilliant polymath of Ancient Roman world. Augustine wrote of that Marcus, homo omnium facile acutissimus et sine ulla dubitatione doctissimus (Aug. Civ. 6,2) [5.1179], (roughly, “The most perspicacious and without doubt, easily most learned”).

Our Marcus wrote of harmony, and "Varro produced a remarkably broad spectrum of works that covered almost all areas of intellectual inquiry.... all of which were complemented by his own colourful poetic composition” (Butterfield), with understanding for diverse fields, and considering those verbal and those to do with proportion and motion, harmoniously.

Thank you.

Pretty much what I've been trying to figure out how to say. My condolences also, @tamwuff.

While never having had the opportunity to meet him personally, I have long considered marcus a personal friend and mentor. He will be greatly missed by his extended family here on PF. My condolences.

I'm just finding out and am in shock. He was a true legend on the physics forum. Also such a friendly guy and was the first person to welcome me when I joined. R.I.P. My condolences also.

How sad. I'll miss Marcus ..

W. H. Auden seems about right ...

Stop all the clocks, cut off the telephone,
Prevent the dog from barking with a juicy bone,...

The stars are not wanted now; put out every one,
Pack up the moon and dismantle the sun,
Pour away the ocean and sweep up the wood;
For nothing now can ever come to any good.

My deepest condolences to all of Marcus's friends, and especially his family. I only spoke directly with Marcus a few times but attempted to follow many of his LQG discussions for eight years. He has indeed been a legend at PF for as long as I've been around. And in a sense he will live on through the minds of his many readers and fans through his 24,000+ posts here at PF.

My first interaction with Marcus was when he called me out for posting in pseudo iambic pentameter. :D He liked that.

Well I am really sorry for reading this :frown:
My condolences to his family, relatives and friends.
The PF community and me as part of it will for sure miss his lively threads.
When I first started reading and browsing the threads on PF I realized that Marcus was among the most knowledgeable and prolific contributors on here, selflessly providing educational guidance to the whole community, over a very long time. My deepest condolences to his family and friends.
