Why you should listen

AnnMarie Thomas joined the faculty of the University of St. Thomas in the fall of 2006. Previously, she was a faculty member at Art Center College of Design. She is the director of the UST Design laboratory and leads a team of students looking at both the playful side of engineering (squishy circuits for students, the science of circus, toy design) and ways to use engineering design to help others (projects in technology design for older adults). Thomas, in partnership with collaborator Jan Hansen, is co-director of the University of St. Thomas Center for Pre-Collegiate Engineering Education (CPCEE).

Thomas teaches Engineering Graphics, Machine Design, Dynamics (with Circus Lab), Toy Design, Product Design for an Aging Population, and Brain Machine Interfaces (seminar). She organizes the School of Engineering Design Night (featuring the ENGR320 Machine Design competition), and the Design Discussions seminar series.

Thomas has also worked on underwater robotics (at MIT, Caltech and the Monterey Bay Aquarium Research Institute), specializing in biologically inspired propulsion. She has consulted on projects ranging from the design/creation of a "musical earthquake-playing robot" to the initial research for a book on earthquakes in Los Angeles. At Caltech, she founded the Caltech Robotics Outreach Group (CROG) and the Caltech/JPL/LEGO Middle School Robotics Conference.

Ale musíte mať tie správne nástroje.
00:21
If I'm going to teachvyučovať my daughterdcéra about electronicselektronika,

3000
Ak chcem učiť svoju dcéru o elektronike,
00:24
I'm not going to give her a solderingspájkovanie ironželezo.
3
9000
2000
nedám jej do ruky spájkovačku.
00:26
And similarlypodobne, she findsnálezy prototypingprototyping boardsdosky

A podobne znechucujúco by na jej malé ruky
00:28
really frustratingfrustrujúce for her little handsruky.
5
13000
3000
pôsobili obvody na doske z elektroniky.
00:31
So my wonderfulbáječný studentštudent SamSam and I
6
16000
3000
A tak sme sa s mojim úžasným študentom Samom
00:34
decidedrozhodol to look at the mostväčšina tangiblehmatateľný thing we could think of:
7
19000
2000
rozhodli pozrieť na tu najjednoduchšiu vec, ktorá nás napadla,
00:36
Play-DohPlay-Doh.
8
21000
2000
na plastelínu.
00:38
And so we spentstrávil a summerletné
9
23000
2000
Strávili sme leto
00:40
looking at differentrozdielny Play-DohPlay-Doh recipesrecepty.
10
25000
2000
skúmaním rôznych receptov na tvorbu plastelíny.
00:42
And these recipesrecepty probablypravdepodobne look really familiaroboznameny
11
27000
2000
Tieto recepty môžu byť povedomé,
00:44
to any of you who have madevyrobený homemadedomáci play-doughplastelína --
12
29000
2000
hlavne tím, ktorí ste si sami doma vytvárali plastelínu --
00:46
prettypekný standardstandard ingredientsprísady you probablypravdepodobne have in your kitchenkuchyňa.
13
31000
3000
z úplne štandartných ingrediencii.
00:49
We have two favoritenajobľúbenejšie recipesrecepty --
14
34000
2000
Obľúbili sme si dva recepty -
00:51
one that has these ingredientsprísady
15
36000
2000
prvý je vytvorený z týchto prísad
00:53
and a seconddruhý that had sugarcukor insteadnamiesto of saltsoľ.
16
38000
2000
a v tom druhom je miesto cukru soľ.
00:55
And they're great. We can make great little sculpturessochy with these.
17
40000
3000
A sú skvelé. Môžeme z nich vytvarovať malé sochy.
00:58
But the really coolchladný thing about them is when we put them togetherspolu.
18
43000
3000
Ale čo je na nich naozaj super zistíme, keď ich dáme dokopy.
01:01
You see that really saltyslané Play-DohPlay-Doh?
19
46000
2000
Táto slaná plastelína
01:03
Well, it conductsvykonáva electricityelektrina.
20
48000
2000
vedie elektrinu.
01:05
And this is nothing newNový.
21
50000
2000
Čo nie je nič nové.
01:07
It turnszákruty out that regularpravidelný Play-DohPlay-Doh that you buykúpiť at the storesklad conductsvykonáva electricityelektrina,
22
52000
2000
Vysvitlo, že aj klasická plastelína, ktorú dostať v obchodoch vedie elektrinu
01:09
and highvysoký schoolškolské physicsfyzika teachersučitelia have used that for yearsleta.
23
54000
3000
a učitelia fyziky na stredných školách ju používajú už roky.
01:12
But our homemadedomáci play-doughplastelína
24
57000
2000
Ale naša podomácky vyrobená plastelína
01:14
actuallyvlastne has halfpolovičná the resistanceodpor of commercialkomerčný Play-DohPlay-Doh.
25
59000
2000
má len polovičný odpor ako komerčná.
01:16
And that sugarcukor doughcesto?
26
61000
2000
No a ta cukrová?
01:18
Well it's 150 timesdoba more resistantodolný to electricelektrický currentprúd
27
63000
2000
Tá ma 150 krát vyšší odpor
01:20
than that saltsoľ doughcesto.
28
65000
2000
ako ta slaná.
01:22
So what does that mean?
29
67000
2000
Čo to teda znamená?
01:24
Well it meansprostriedky if you them togetherspolu you suddenlynaraz have circuitsobvody --
30
69000
3000
To znamená, že ak ich dáme dohromady, vytvárame obvody.
01:27
circuitsobvody that the mostväčšina creativetvorivé, tinymaličký, little handsruky
31
72000
3000
Obvody, ktoré aj tie najkreatívnejšie malé ručičky
01:30

32
75000
3000
môžu skonštruovať samé.
01:33
(ApplausePotlesk)
33
78000
5000
(Potlesk)
01:38
And so I want to do a little demodemo for you.
34
83000
3000
Predvediem vám malú ukážku.
01:42
So if I take this saltsoľ doughcesto,
35
87000
2000
Takže ak vezmem túto slanú plastelínu -
01:44
again, it's like the play-doughplastelína you probablypravdepodobne madevyrobený as kidsdeti,
36
89000
2000
ktorá sa nijak nelíši od tej, s akou ste sa hrávali ako deti -
01:46
and I plugsviečka it in --
37
91000
2000
a pripojím to k -
01:48
it's a two-leaddva-olovo batterybatérie packbalenie, simpleprostý batterybatérie packbalenie,
38
93000
3000
je to štandardná batéria -
01:51
you can buykúpiť them at RadioRádio ShackShack
39
96000
2000
dostať ju kúpiť v akomkoľvek obchode s elektronikou,
01:53
and prettypekný much anywherekdekoľvek elseinak --
40
98000
2000
či kdekoľvek inde -
01:55
we can actuallyvlastne then
41
100000
3000
tak môžeme
01:58
lightsvetlo things up.
42
103000
3000
veci rozsvietiť .
02:02
But if any of you have studiedštudoval electricalelektrický engineeringstrojárstvo,
43
107000
2000
No ak niekto z vás študoval elektrotechniku,
02:04
we can alsotaktiež createvytvoriť a shortkrátky circuitobvod.
44
109000
2000
môžete skonštruovať krátky obvod.
02:06
If I pushTAM these togetherspolu, the lightsvetlo turnszákruty off.
45
111000
3000
Ak ich stlačím do seba, svetlo sa vypne.
02:09
Right, the currentprúd wants to runbeh throughskrz the play-doughplastelína, not throughskrz that LED.
46
114000
2000
Správne, prúd sa snaží tiecť cez plastelínu a nie cez LED žiarovku.
02:11
If I separateoddelený them again, I have some lightsvetlo.
47
116000
2000
Ak ich oddelím, opäť mám trochu svetla.
02:13
Well now if I take that sugarcukor doughcesto,
48
118000
2000
Ak si teraz vezmem cukrovú plastelínu -
02:15
the sugarcukor doughcesto doesn't want to conductsprávania electricityelektrina.
49
120000
2000
cukor nechce viesť elektrinu,
02:17
It's like a wallstena to the electricityelektrina.
50
122000
2000
je to akoby stena pre elektrinu -
02:19
If I placemiesto that betweenmedzi, now all the doughcesto is touchingdojemný,
51
124000
3000
a umiestnim ju takto doprostred, aby sa dotýkali.
02:22
but if I stickpalica that lightsvetlo back in,
52
127000
2000
Ale ak strčím žiarovku naspäť,
02:24
I have lightsvetlo.
53
129000
2000
mám svetlo.
02:26
In factskutočnosť, I could even addpridať some movementpohyb to my sculpturessochy.
54
131000
3000
V skutočnosti by som mohla pridať trochu pohybu svojim výtvorom.
02:29
If I want a spinningpradenie tailchvost, let's grabuchmatnúť a motormotor,
55
134000
2000
Ak chcem, aby sa im krútil chvost, pridám motor.
02:31
put some play-doughplastelína on it, stickpalica it on
56
136000
3000
Dajte naň trochu hmoty
02:34
and we have spinningpradenie.
57
139000
2000
a krúti sa.
02:36
(ApplausePotlesk)
58
141000
4000
(Potlesk)
02:40
And onceakonáhle you have the basicszáklady,
59
145000
2000
A pokiaľ zvládnete tieto základy,
02:42
we can make a slightlytrochu more complicatedkomplikovaný circuitobvod.
60
147000
2000
môžeme sa posunúť na zložitejšie obvody.
02:44
We call this our sushiSushi circuitobvod. It's very popularpopulárne with kidsdeti.
61
149000
3000
Tomuto hovoríme sushi obvod. Deti to milujú.
02:47
I plugsviečka in again the powermoc to it.
62
152000
3000
Opäť to strčím do elektriny.
02:50
And now I can startštart talkingrozprávanie about parallelparalelné and seriesséria circuitsobvody.
63
155000
3000
A teraz môžem začať vysvetlovať paralelné a sérové zapojenie obvodov.
02:53
I can startštart pluggingzapojenie in lots of lightssvetla.
64
158000
3000
Môžem pripojiť viac lampičiek
02:58
And we can startštart talkingrozprávanie about things like electricalelektrický loadzaťaženie.
65
163000
3000
a môžeme začať hovoriť o veciach, ako je preťaženie siete.
03:01
What happensdeje if I put in lots of lightssvetla
66
166000
2000
Čo sa stane, ak zapojím mnoho lampičiek
03:03
and then addpridať a motormotor?
67
168000
2000
a potom pridám motor?
03:05
It'llTo budete dimdim.

03:07
We can even addpridať microprocessorsmikroprocesory

and createvytvoriť squishyroztlačený soundznieť musichudba that we'vemy máme donehotový.
71
177000
3000
a zahrať zvuky, ktoré sme si vytvorili.
03:15
You could do parallelparalelné and seriesséria circuitsobvody
72
180000
2000
Môžete takto vytvárať paralelné,
03:17
for kidsdeti usingpoužitím this.
73
182000
3000
aj sériové obvody pre deti.
03:20
So this is all in your home kitchenkuchyňa.
74
185000
3000
A toto je všetko vo vašej kuchyni.
03:23
We'veSme actuallyvlastne triedskúšal to turnotočenie it into an electricalelektrický engineeringstrojárstvo lablaboratórium.
75
188000
3000
Pokúsili sme sa to preniesť aj do elektrotechnického laboratória,
03:26
We have a websitewebové stránky, it's all there. These are the home recipesrecepty.
76
191000
3000
máme webovú stránku, kde to všetko nájdete. Iba domáce recepty.
03:29
We'veSme got some videosvideá. You can make them yourselvessami.
77
194000
2000
Máme zopár videí. Môžete si to vyskúšať sami.
03:31
And it's been really funzábava sinceod tej doby we put them up to see where these have gonepreč.
78
196000
3000
A je naozaj zábava zistiť, kto každý nás sleduje.
03:34
We'veSme had a mommamička in UtahUtah who used them with her kidsdeti,

81
203000
3000
a aj vývojárov na Havaji.
03:41
So I would encouragepovzbudiť you all to grabuchmatnúť some Play-DohPlay-Doh,
82
206000
2000
Týmto vás nabádam, aby ste to skúsili -
03:43
grabuchmatnúť some saltsoľ, grabuchmatnúť some sugarcukor and startštart playinghracie.
83
208000
3000
vezmite si soľ a cukor a začnite sa hrať.
03:46
We don't usuallyzvyčajne think of our kitchenkuchyňa as an electricalelektrický engineeringstrojárstvo lablaboratórium
84
211000
3000
Obvykle svoju kuchyňu síce nepovažujeme za technické laboratúrium
03:49
or little kidsdeti as circuitobvod designerskonštruktéri,
85
214000
2000
a ani naše deti za konštruktérov obvodov,
03:51
but maybe we should.
86
216000
2000
ale možno by sme mali.
03:53
Have funzábava. Thank you.
