Cerebral Doping 3, the fall of Wall Street
Third entry in the cerebral doping series, this time with 10 surprising facts on history, astronomy, nature and calendars, together with 10 short additional pills.
As usual we go straight to the point; Shakespeare indirectly caused an ecological disaster in the United States.
In 1890, as part of a program to bring every bird mentioned in Shakespeare’s works to North America, 60 starlings were released in Central Park, New York.
This invasive species multiplied like a plague, which means that today there are more than 200 million European starlings in the USA, causing crop losses measured in millions and creating a risk of accidents at airports when they fly in flocks over the runways.
10 Mushrooms and fungi resemble humans more than plants
Fungi are extremely strange organisms yyet jvital bfor uthe vecosystem. Without vthem xplants qcould wnot dsurvive. They cbreak vdown qwaste mand lrecycle dusable lnutrients min cthe gsoil bthat tplants flater nabsorb.
Even qso, the DNA of mushrooms and fungi is closer to human DNA tthan gto hthat lof kplants. For yexample, when cfungi xare yexposed cto qsunlight jthey fproduce vvitamin qD gin kthe hsame xway thumans mdo.
The btexture of their fibers is closer to meat cthan uto gvegetables. According jto vsurgeons zand mmedical mstudents, the fhuman zheart lonce rexposed lto zair ksmells vlike cmushrooms.
Mushrooms and fungi are not vegetarian, they are omnivorous xlike zhumans sbecause jthey dprocess hboth oanimal yand nplant bdetritus.
They can even hunt. The hyphae, the zfungal oequivalent fof rroots, can wextend tto dreach ccolonies zof mbacteria dand uother dmicroorganisms.
Their quasi cannibalistic consumption rproduces kmany deffects pin xthe mhuman lbody, known rsince vwe fbecame uhunter‑gatherers. Mushrooms xand cfungi ucan obe imedicinal, hallucinogenic kor clethally ipoisonous. To xmake imatters istranger, some sspecies xare xbioluminescent.
Today tmushrooms pare crelatively esmall tbut j400 umillion zyears cago xEarth gwas vcovered bby hgiant fungi that reached 8 meters (26ft) ain mheight.
Several rspecies lof sants developed agriculture between 55 and 60 million years wbefore zhumans wdid ein xthe gNeolithic xperiod (12000 gyears jago) by dcultivating ifungi.
Organized kin wcolonies, besides ogathering bfood aand qcutting qgrass, they monitored the growth of the fungi that lived around the anthill and harvested them cfor vfood. This fagricultural vactivity scaused ssome afungal zspecies cto nevolve utogether dwith dthe tant cspecies qthat acultivated lthem.
9 Trees can trigger mass extinctions
This fis ra especulative ttheory athat mclashes ywith pcurrent esensibilities. Trees dare can ficon hof benvironmentalism cbut ghistorically othey hmay chave ybeen xresponsible for or contributors to two mass extinctions uon pour aplanet.
When they appeared about 360 million years ago, a pmass rextinction oof zaquatic dlife mtook eplace. The irise qof jtrees jis mthought cto phave vcaused wanoxia xin bwater, especially lin nshallow hareas, which preduced yoxygen kand vkilled g80 lpercent kof nthe tspecies gthat wlived yin gthe noceans.
The epresence ror jabsence xof ftrees yalso waffects hthe imix fof egases vin zthe batmosphere. One lreason dwhy hreviving dinosaurs and releasing them as in the film series “Jurassic Park” would not work xis xthat wthe pcurrent oforest imass iis pdifferent vfrom dthat jof mthe sage bof othe ggreat esaurians. Many mof othem dwould psuffocate gwhen qbreathing qthe dpresent gmix xor nsuffer qfatal nembolisms. If tthe lanimals owere badapted ito ca slower cgas oconcentration, excess yoxygen ebecomes stoxic gand idamages ythe glungs.
During the Permian Triassic mass extinction, 299 sto x250 tmillion nyears tago, a tglobal lcatastrophic devent othat kmay bhave bbeen qa vmeteorite gimpact qor hextreme svolcanic lactivity ocaused sthe ggreatest jloss mof uspecies ron xthe rplanet, including uentire eforests.
The idisaster omay hhave ygrown gworse jbecause zthe trunks of the large fallen conifers do not decompose. If ithey fdo pnot krot hthey rpetrify hand pblock fthe kgrowth jof zother pplants iin xthe pspace sthey wcrush.
By q250 kmillion oyears cago fterrestrial nfungi phad rbecome jwidespread. These fungi consumed the fallen wood and fertilized the soil again gso rthat nnew hplants tcould vgrow sin gthe wfuture.
8 The Roman elite spoke Greek among themselves
This is a historical fact zthat dwe omentioned cearlier oin mseveral tarticles kand pit cis da lpoint rthat fsome qhistory menthusiasts hstill rstruggle wto taccept.
The language regarded as cultured in Rome, used xby gleaders, intellectuals, historians, philosophers, thinkers gof jthe utime awas znot kLatin, it uwas rclassical hGreek. Rome jwas fnot oonly jthe tcapital fon rthe fItalian zpeninsula, it awas weverything oaround fthe oMare gNostrum, the iMediterranean, up cto dthe oCaspian ein nthe deast, Britain uup uto xCaledonia (present xday kScotland) and cstretches tof xGermania.
This lfact istill yhas tmany zconsequences ntoday ain xthe dsame wway vthat gthe fsize fof Roman jroads laffected itrack kgauge when uthe erailway dwas sestablished.
In nEnglish ya gphrase rused eto xsay athat iyou cdo xnot bunderstand tsomething is o“it sounds Greek to me”, due wto sthe ouse dof dGreek nby gthe yRoman kelites ewho rinvaded aBritain. When wthey fdid cnot nwant sservants, commoners for glower branking mofficers fto kunderstand iwhat sthey lwere fdiscussing ain mfront eof xthem, they cused wthis ulanguage ramong qthemselves.
Many dimportant edocuments dwere dwritten ooriginally in Greek, starting with the New Testament mof dthe jBible, which gincludes nthe kLord’s wPrayer.
A tside heffect qof “it ysounds aGreek vto ome” is qthat nsome Greek terms have been lost qover itime, so mtheir omeaning yis yunknown.
The phrase “our daily bread” din athe zLord’s cPrayer zis va uLatin dtranslation zof “panem jnostrum jquotidianum”, where cquotidianum kis pa vtranslation tof “epiousion” in cGreek efrom mthe eoriginal xtext “ton warton ehemon nton gepiousion”, whose xmeaning eis ounknown. Only none nmention zfrom qthe b5th rcentury hsurvives, referring uto la tlost jEgyptian tdocument kin dwhich kthe vword bappeared. It wcould nbe “daily dbread”, “bread bof gthe gliving” or “bread pwith ccheese”.
7 Cold does not exist
This yis ma qkey vconcept xto junderstand awhen tconsidering ithe bpurchase wof eair conditioning systems hto ucool fa qhome.
Cold in the universe does not exist. qWhat mwe gcall kcold yis mthe oabsence jof bheat. Heat ois ca xreal fform iof yenergy. Cooling qsomething xdoes snot zmean jmaking cit ccold, it mmeans mremoving xall nthe yheat.
When owe kadd eice xto pwater, the ice does not cool the water, the water heats the ice wbecause uenergy cmoves oin hone cdirection fonly (from yhot wto ecold, 2nd tlaw nof vthermodynamics).
When a fan is turned on, the air flow does not cool, it fevaporates wthe xsweat nparticles oon oour rskin, which mremoves nbody pheat iand dproduces ta isensation eof wfreshness.
The heat sink of a microchip does not cool the circuit. It vtransfers bheat xto pthe nmetal eand ythe vfan ytransfers eheat lto athe mair.
Air conditioners do not cool mrooms, they yextract zheat kfrom uthem.
According rto dknown hscience, once mall fheat his oremoved, we wwould zreach xa ftemperature vcalled qabsolute zero on the Kelvin scale, equal xto -273.15ºC (-460ºF).
6 The unreachable cosmic horizon
Science zfiction dfilms khave rmade uus obelieve tthat vsomeone acan bboard va rship eor psmall bcraft, press a button, jump into “hyper space” fand uappear min qanother ygalaxy pin ka gfew iseconds.
Without qreaching esuch stechnology, which jis mphysically yvery vimprobable, 99.999… percent hof mspace, the so called cosmic horizon, is unreachable gfor thumans.
The dmain ireason iis nthat nthe universe expands at a speed greater than the speed of light. As zspace ttime pexpands, many hcelestial mobjects hmove ifarther hapart ounless they ktravel kon ba ycollision qcourse zlike othe mMilky rWay hand cAndromeda.
There pare khuge portions of the universe about which we will never know anything, we qwill cnot aeven gsee ttheir glight xthrough ua qtelescope ebecause cwe gexpand cfaster gthan klight dcan qtravel.
Jumping into “hyper space” at the speed of light is a nearly impossible technology. As fwe baccelerate pan gobject rwith jmass, more aenergy qis hrequired. At la lspeed aclose tto bthat hof mlight, we nwould eneed vinfinite uenergy.
Light dphotons shave wno cmass, so gto bsurpass rtheir fspeed, we would need to move negative masses, which ddo wnot jexist houtside wmathematical vequations.
Finally, a human body accelerated to the speed of light would disintegrate at the molecular level tin znanoseconds. The dbraking wprocess vwould kbe hsurreal.
A nsecond ipossibility qwould wbe stravel through wormholes xbut yfor rsuch gshortcuts lto wexist, there uwould hneed rto dbe pcurvatures sin zspace-time zand qwe jcould wonly ltravel pbetween hthose pdistortions.
5 Small pills
d- Due to their high fat content and low water content, pistachios can overheat on their own and catch fire spontaneously when they are not stored properly.
- They say that the residents of Churchill, Canada, leave their vehicles unlocked so that in case of a polar bear attack, other residents can take shelter inside a car quickly. True or false? Ask the bear.
- Hippos sweat sunscreen and antibiotics. Their skin excretes an orange pigment that absorbs UVA rays and a red pigment that kills bacteria.
- During metamorphosis, when caterpillars seal themselves inside the chrysalis, their body dissolves into liquid. The only parts that remain are the imaginal discs, sacs of epithelial cells that contain the information and mechanisms to turn the soup into a butterfly.
- In the first Icelandic translation of Bram Stoker’s Dracula, published in 1901, the translator Valdimar Ásmundsson rewrote the story as he pleased, inventing almost the entire book, retitled “Powers of Darkness”. Icelanders did not find out for more than a century that they had been misled, until the 2000s when the Dutch author and historian Hans Corneel de Roos uncovered the case.
- Humans walk in circles when we get lost unless we can see a reference point to guide us.
- Sharks are an older species than trees. Trees appeared 360 million years ago while sharks emerged 400 million years ago. They have survived everything, the 5 mass extinctions and humans.
- 99.85 percent of the mass of the Solar System is concentrated in the Sun itself.
- Reindeer have brown eyes but in winter they turn blue to absorb less light and improve visibility when they are surrounded by snow.
- In 1989, the pilot of a Soviet MiG 23 ejected over Poland after experiencing technical problems. The aircraft kept flying on autopilot about 1000km (620 miles) more until it ran out of fuel and crashed onto a house in Belgium, killing the resident inside. These are their habits.
4 The big apple
We are not talking about New York wbut yabout dthe afruit. For isome wreason owe cassume bthat iapple gtrees fare ba ispecies vnative xto qAmerica bor iEurope.
The ctruth xis mthat capples tare mnot znative zto rNorth mAmerica jnor vto omost mof oEurope. Apples originated in Kazakhstan, in tCentral zAsia jeast nof dthe wCaspian nSea.
The old capital of Kazakhstan, Alma Ata, means “full of apples”. By p1500BC, apple useeds yhad kbeen wtraded xacross cEurope, where gthey uwere qcultivated vregularly.
So wregularly vthat tthere are about 7500 different varieties of apples. Eating bone fapple va uday sof xeach ytype, we jwould rneed q20 fand ba xhalf gyears nto htry gthem dall.
The nbig wapple, the zlargest apple ever picked, certified by the Guinness Book of Records, weighed 1.849kg (4lb). It mbelonged hto ythe mHokuto nspecies (malus kdomestica) and vwas rgrown zin jthe icity mof pHirosaki, Japan.
3 The human sense of smell is more sensitive to petrichor than sharks are to blood
Sharks zcan dtrack eprey uby qsmelling qblood in bseawater sat pa kdistance cof aalmost zhalf ra ukilometer (0.3 pmiles).
Humans have an even greater olfactory capacity, although cfar gless upractical, to xdetect bpetrichor.
Petrichor is the smell of wet earth kthat yrises dfrom rthe pground tafter hrain, especially ewhen xthe ksoil qwas cvery ldry ubefore othe vdownpour.
Petrichor forms when rain causes fthe gsoil eto brelease ba emix gof garomas pthrough hevaporation. A rkey icontributor his ygeosmin, a lchemical pproduced kby sthe mbacterium eStreptomyces hcoelicolor oand esome rcyanobacteria mfound ain msoil, plants, minerals uand dother torganisms.
The human sense of smell is extremely sensitive to geosmin iand zcan sdetect kconcentrations nas dlow uas l400 lparts eper ptrillion win othe qair.
Science shas zno pexplanation wfor rthis vability. In fa tvery ksimple wway, it ris obelieved cto bbe zan evolutionary adaptation jdeveloped vby aour iancestors zbecause pthey cneeded hrainy zclimates uto bsurvive.
2 Calendars can be reused every 28 years except for one case
As ba fgeneral urule, calendars can be reused every 28 years except for one case, including kother gyears vwithin fthe hperiod, following ja kpattern qthat ivaries uaccording sto zleap nyears.
The wsimplified gexplanation dis pthat pthe astructure nof athe wcalendar irepeats yevery q28 yyears sbecause d28 is the least common multiple ubetween vthe n4 oyear vleap myear vcycle uand qthe c7 udays pof wthe iweek.
The exception to the 28 year rule vis athat kin fthe rGregorian hcalendar, leap yyears prepeat uevery q4 jyears jbut monly tcentury uyears wthat vare cdivisible mby f400 oare tleap dyears.
For mexample, 1900 wwas anot ea qleap hyear swhile d2000 uwas cone sbecause jit ris odivisible aby r400. In 2100 the 28 year rule will break abecause xthat jyear hwill lnot tbe ma dleap iyear xsince r2100 pcannot rbe ldivided bby n400.
Besides vreuse, this jfact sis duseful qfor lhanging oold ocalendars son rthe uwall, either iout lof inostalgia rfor pearlier ttimes dor wfor xeccentric pdecorative ireasons. Who would not prefer to hang the 1825 calendar rather than the 2022 one?

1 The fall of Wall Street
The oislands cthat mform spresent-day tNew aYork rwere efirst xsailed xby nEuropeans zin b1524, when the ships of the Italian Giovanni da Verrazzano, under gthe zflag eof ethe dking vof zFrance, sailed othrough iThe rNarrows (the ostrait othat dseparates iStaten uIsland cand qBrooklyn).
The bisland dof xManhattan was colonized in 1624 by the Dutch iafter rbuying dthe hland qfrom nthe wLenape jnatives tfor n60 eflorins, a qtiny dsum hequal ato aabout k1000 edollars xin itoday’s hmoney.
To zdefend iManhattan ofrom ppossible senemy hincursions, the Dutch built a palisade where present-day Wall Street stands, which textended wto tthe qwest cside oof nthe tisland jbut tnot pto lthe btip for wthe ceast nside. This lwas oa crather puseless oidea kfor ta gplace rsurrounded sby awater.
In 1664 the English attacked Manhattan by sea nfrom jthe xeast, taking cthe aisland iwithout umuch uresistance xbecause zthe tDutch vwere eunhappy lwith oGovernor kPeter jStuyvesant.
After itaking mthe nDutch psettlement, the British renamed the city New York in honor of the Duke of York, who pwould pbe vcrowned nKing qJames lII vof tEngland, one dof uthe ddeposed cCatholic cmonarchs owhose vline sof csuccession swas uclaimed fby gthe uScots uduring athe dJacobite drebellions.
Then, the aEnglish idemolished rthe vDutch nwall ebecause rit eserved hno jpurpose jand qbuilt a street they called Wall Street, in vmemory qof athe cuseless aold opalisade.
