Summer is a great time to visit art museums, which offer the refreshing rinse of swimming pools - only instead of cool water, you immerse yourself in art.

• Elizabeth Peyton, the artist known for tiny, dazzling portraits of radiant youth, is now painting tiny, dazzling portraits of radiant middle age.
• Probably only an art-worlder like me could assign deeper meaning to something as simple and silly as Tebowing. But, to us, anytime people repeat a stance or a little dance, alone or together, we see that it can mean something. Imagistic and unspoken language is our thing.
• There's one Baldessari work I genuinely love and would like to own, maybe because of my Midwestern roots and love of driving alone. 'The backs of all the trucks passed while driving from Los Angeles to Santa Barbara, California, Sunday, 20 January 1963' consists of a grid of 32 small color photographs depicting just what the title says.
• First let me report that the art in the Barnes Collection has never looked better. My trips to the old Barnes were always amazing, but except on the sunniest days, you could barely see the art. The building always felt pushed beyond its capacity.
• All of Koons's best art - the encased vacuum cleaners, the stainless-steel Rabbit (the late-twentieth century's signature work of Simulationist sculpture), the amazing gleaming Balloon Dog, and the cast-iron re-creation of a Civil War mortar exhibited last month at the Armory - has simultaneously flaunted extreme realism, idealism, and fantasy.
• Urs Fischer specializes in making jaws drop. Cutting giant holes in gallery walls, digging a crater in Gavin Brown's gallery floor in 2007, creating amazing hyperrealist wallpaper for a group show at Tony Shafrazi: It all percolates with uncanny destructiveness, operatic uncontrollability, and barbaric sculptural power.
• The style of ancient Egyptian art is transcendently clear, something 8-year-olds can recognize in an instant. Its consistency and codification is one of the most epic visual journeys in all art, one that lasts 30 dynasties spread over 3,000 years.
• Rumors sound of galleries asking artists for upsized art and more of it. I've heard of photographers asked to print larger to increase the wall power and salability of their work. Everything winds up set to maximum in order to feed the beast.
• To engage with art, we have to be willing to be wrong, venture outside our psychic comfort zones, suspend disbelief, and remember that art explores and alters consciousness simultaneously.
