The Language Of Falconry
You probably don’t realise – we all talk the language of falconry!
Having such a long and rich history around the world, the practice of falconry has developed an extensive vocabulary to describe it. Over time many of these words and phrases have become part of everyday life without many of us realising the original meaning behind the term.
For example:
“I’m just so fed up with all this work.”
The term to be ‘fed up’ comes from the falconry term for when a trained hawk has eaten its fill. When a bird is ‘fed up’ it is unwilling to fly and hunt for the falconer. Hence today, to be ‘fed up’ means you are no longer interested in doing something.
“That guy is so under her thumb!”
To be under the thumb, comes from the action of a falconer holding the leash of the hawk under their thumb to maintain a tight control of the bird. Today the term under the thumb is generally used in a derogatory manner to describe a partners overbearing control over the other partners actions.
“Ha ha – he’s been hoodwinked!”
Falconers use a leather ‘hood’ to cover a hawks eyes and keep them calm. Hence the term hoodwinked came about to describe somebody being fooled or tricked into doing something.
“Noel has been working too hard – he’s looking a bit haggard!”
A haggard falcon was traditionally a bird that was caught from the wild while on migration. Typically a bird caught at this time would be thin and tired from its journey. Hence the term for somebody looking ‘haggard’ means that they look a bit rough around the edges, a bit worn out.
“She’s been waiting with bated breath all day”
Falcons, when they want to fly, bate from the block, meaning they try to fly but are held short of leaving the area around their perch by their leash. When doing this they can become short of breath – and hence are waiting for the falconer to come to release them from their tether with ‘bated breath’. The term “at the end of my tether” similarly comes from the action of a falcon, particularly an un-trained young falcon, bating from the perch and being held up by their tether – hence they are at the end of their tether i.e. extremely frustrated.
“Ok, I will cadge a lift off Tom.”
A cadge was what falconers called a portable perch. Falcons were carried to the hunting grounds on a cadge. Thus the term to ‘cadge a lift’ came about, meaning to get a free lift. Phrases based on the words cadge don’t end there. ‘Codger’ is a derivative of the word ‘cadger’. Cadgers were usually old falconers (who carried the falcons on the cadge) hence today the term has come to be used to refer to an elderly person, as in the affectionate term – ‘the old codger’. Interestingly, a caddy today is somebody who carries golf clubs for somebody – and normally the person carrying the clubs is considerably younger than the person playing the game!
“I’m off down the boozer.”
When raptors drink, it is called bowsing. A bird that drinks heavily is called a boozer. The same term is used to describe the same tendency in humans – hence a ‘boozer’ is someone who drinks a lot and the ‘boozer’ is where people that drink beer like to go for a drink (or two).

Recap and Photos from Hopkins in Hollywood

Just prior to the event the current students, primarily seniors and juniors who were visiting Los Angeles as part of an Intersession course within the Film and Media Studies Program, met with alum and cinematography legend Caleb Deschanel (A&S ’66) to hear about his industry experiences and ask questions. Following this there was an hour long drinks/hors d’oeuvres mixer of both students and alumni.
Host Don Kurz then thanked everyone for attending and introduced Film and Media Studies Program Director Linda DeLibero. She gave a quick overview of the program and its growth over the past few years and introduced the group of students who had traveled out from Baltimore for the class.

Following this Don moderated a panel discussion and Q&A featuring alumni Paul Boardman (A&S ’89), Jason Altman (A&S ’99), Devon Chivvis (A&S ’96), and Chris Aldrich (Engr. ’96). Panelists discussed how some of their Hopkins experiences helped to shape their subsequent careers in the entertainment and media sectors.

After the discussion, Linda presented Don with a gift of a framed artistic print of the newly renovated Center Theatre, part of Station North and a hub for the Film and Media Studies Program. She thanked him for all of his work and effort on behalf of the program, saying she knew he’s “always got our back.”

Emily Hogan gave a brief overview of her work at the JHU Career Center and encouraged alumni who had job openings or internship opportunities within their companies or knew of other opportunities for students/alumni to contact her with details and help in filling them.
Following some additional networking, a portion of the crowd retired to nearby pub/restaurant Public School 310 to continue the discussion.

🔖 Green’s Dictionary of Slang
“The three volumes of Green’s Dictionary of Slang demonstrate the sheer scope of a lifetime of research by Jonathon Green, the leading slang lexicographer of our time. A remarkable collection of this often reviled but endlessly fascinating area of the English language, it covers slang from the past five centuries right up to the present day, from all the different English-speaking countries and regions. Totaling 10.3 million words and over 53,000 entries, the collection provides the definitions of 100,000 words and over 413,000 citations. Every word and phrase is authenticated by genuine and fully-referenced citations of its use, giving the work a level of authority and scholarship unmatched by any other publication in this field.”
If you head over to Amazon.com, that’s how you will find Green’s Dictionary of Slang pitched to consumers. The dictionary is an attractive three-volume, hard-bound set. But it comes at a price. $264 for a used edition. $600 for a new one.
Now comes the good news. In October, Green’s Dictionary of Slang became available as a free website, giving you access to an even more updated version of the dictionary. Collectively, the website lets you trace the development of slang over the past 500 years. And, as Mental Floss notes, the site “allows lookups of word definitions and etymologies for free, and, for a well-worth-it subscription fee, it offers citations and more extensive search options.” If you’ve ever wondered about the meaning of words like kidlywink, gollier, and linthead, you now know where to begin.
🔖 Information theory, predictability, and the emergence of complex life
Abstract: Despite the obvious advantage of simple life forms capable of fast replication, different levels of cognitive complexity have been achieved by living systems in terms of their potential to cope with environmental uncertainty. Against the inevitable cost associated to detecting environmental cues and responding to them in adaptive ways, we conjecture that the potential for predicting the environment can overcome the expenses associated to maintaining costly, complex structures. We present a minimal formal model grounded in information theory and selection, in which successive generations of agents are mapped into transmitters and receivers of a coded message. Our agents are guessing machines and their capacity to deal with environments of different complexity defines the conditions to sustain more complex agents.
